Main characters.
Jake Peralta.
Andy Samberg portrays Detective Jacob "Jake" Sherlock Peralta, a talented but childish detective. Peralta often exhibits "class clown" traits, constantly pulling pranks and making immature jokes at the expense of his colleagues, particularly his partner Amy Santiago. He is fun-loving and sarcastic, but is often motivated by his emotions more than his colleagues. Despite his goofiness, Peralta is extremely smart, perceptive and quick thinking, and as such has the best arrest rate in the precinct. In the pilot, Terry Jeffords explains to Captain Holt that Peralta is his best detective, that he likes putting away bad guys, and that he loves puzzles, although "the only puzzle he hasn't solved is how to grow up." In "Game Night", Peralta tells Holt that he changed his middle name legally to Sherlock. As of season seven, he is 38 years old and has been a detective with the 9-9 since 2005.
Jake's father abandoned his family during his childhood, and he feels a strong tie to memories involving his father as a result, such as his favorite Brooklyn pizza joint. He also initially refuses to celebrate Thanksgiving, since he associates the holiday with his father's absenteeism. He had a strong emotional tie to his muscle car, a 1967 Ford Mustang, which he bought outright on his first day as a cop and always carried a positive association for him, until he sold it to help pay for Terry's new child. He often quotes and makes references to his favorite movie trilogy, "Die Hard". In "Boyle-Linetti Wedding", it is revealed that Jake is Jewish, having lost his childhood sweetheart Jenny Gildenhorn to Eddie Fung at his Bar Mitzvah.
Peralta's best friend is Charles Boyle, who works with him at the precinct and admires Peralta; Charles also encourages his eventual romance with Santiago. Peralta and Gina Linetti are childhood friends, and he helped Gina get a job at the precinct as a civilian administrator. Diaz and Peralta were classmates at the police academy.
Jake began his career as a patrol officer with the 74th Precinct and was partnered with Stevie Schillens; the two nicknamed themselves the "Beatsie Boys". In 2016, Jake was forced to arrest Stevie, now a detective with the neighboring 98th Precinct, for planting evidence. 
While Jake initially struggles with Captain Holt's strict management style, he eventually matures under Holt's supervision and comes to see the captain as a father figure; even calling him "Dad" on many occasions. In "The Oolong Slayer", Jake achieves his lifelong dream to catch a serial killer, the Oolong Slayer, but gives up the credit for the arrest to the Chief of Brooklyn Detectives in exchange for effecting Holt's transfer back to the 99th Precinct.
At the end of season four, Jake and Rosa Diaz are framed by their idol Lt. Melanie Hawkins and are jailed. After months in prison at the beginning of season five, the two are freed thanks to the precinct exposing Hawkins' crimes. Although he is eager to return to work, his time in prison left him with post-traumatic stress and a newfound empathy that begins to affect his job performance.
In the season 5 episode "Two Turkeys", Jake's father Roger reveals that Jake has three half-sisters, along with an unknown number of half-brothers. He later meets one of his half-sisters, Kate, in the episode "DFW".
Peralta continuously pranks and teases his partner Amy Santiago, masking his secret romantic feelings for her. Peralta confesses his feelings to her in "Charges and Specs" before going undercover for a mafia operation. His romantic feelings for her develop further throughout season two and they share their first kiss in the season finale, "Johnny and Dora". Jake and Amy start dating in "New Captain" and decide to move in together in "Greg and Larry", but don't make it official until season four's "The Fugitive". Jake proposes to Amy at the end of their annual Halloween heist in HalloVeen and the two are later married by Captain Holt in the season five finale. In season 7, Amy becomes pregnant with their child. Their son McClane "Mac" Peralta (who was named after John McClane from "Die Hard") is born in the season 7 finale.

In "Stakeout", he received a commendation for his work on Rosa's drug task force.
Rosa Diaz.
Stephanie Beatriz portrays Detective Rosalita "Rosa" Diaz, a smart, tough, aloof, and mysterious detective. She attended parochial school, later studied ballet, and was a classmate of Jake's in the police academy. When she was younger, the pressure for her to succeed at ballet school eventually led her to commit several crimes, including "beating up other ballerinas," before landing in juvenile detention. Her parents provided little support, leaving Rosa to turn her life around by herself. 
Though Diaz is a loyal and effective member of the squad, her anger management issues and lack of empathy terrify most of her coworkers which Terry and Holt attempt to use to increase precinct efficiency. If Rosa is too angry people are even too scared to walk past her to the bathroom. She is highly secretive about her personal life – should anyone discover a secret of hers, she normally threatens them with death should they disclose it. It is also made clear that she does not stay in her apartments for long periods of time, and her neighbors know her by both a different name and a completely different personality. In the Episode "Greg and Larry" Rosa's neighbors know her as a chatty girl named Emily Goldfinch. When she attempts to run from prison she creates an alias for herself "Rachel Weinstein". In the episode "Greg and Larry" Rosa also suggests that her real identity is even hidden from the nine nine. As revealed in "Cop-Con", she and Amy are younger than most of the other precinct members as they are hurt by a device that emits a loud noise to those under 35, whereas Jake and Boyle only pretend to be affected by it. In "White Whale", she tells Amy that she not only attended ballet school but she went to medical school, business school and has a pilot's license.
Rosa also attended catholic school and when Terry did some digging he realised that she had left due to being offered a position in prestigious ballet school. Rosa initially denied this before admitting it was true, also stating she was kicked out for beating up the other ballerinas. She has a background in gymnastics, is very skilled at yoga and is also an archer. In her spare time Diaz also fixes up old cars to sell to famous people.
In season two, Rosa dates Captain Holt's nephew, Marcus, but breaks up with him in season three. Later in the season, she finds love with former undercover detective Adrian Pimento; the two get engaged in "Paranoia" while chasing a drug dealer through an alley, but their wedding is delayed when Pimento is targeted by Figgis and forced to flee, making use of the fact that the mob already thinks he is dead. Once he returns, they try to have their wedding the next day, but decide to slow down after realizing they were rushing their relationship; however they did decide to keep the gifts and stay together.
At the end of season four, Rosa and Jake are framed by their idol Lt. Melanie Hawkins and are arrested. After months in prison at the beginning of season five, the two are freed thanks to the precinct exposing Hawkins's crimes. Following her months of isolation, she starts spending more time with her family and ends her relationship with Pimento. While on the road trip home she is on the phone to a woman whom she calls babe, and Charles hears this, forcing Rosa to admit to him that she is bisexual. Later in the season, she comes out as bisexual to the precinct and her family, and has a brief relationship with an unseen woman that the squad never meet or learn the name of, nicknamed "Becky". She has a brief flirtation with one of Gina's friends, but this does not lead anywhere. On the day of Jake and Amy's wedding, she and Terry meet a cab driver named Alicia that she becomes interested in. The two begin a relationship off-screen. However, it's short-lived, as Rosa mentions in "The Tattler" that they broke up because Alicia was moving to London. However she did have another partner at the time and Charles helped her decide between the two "Boyle style" she ended up with "Cus Cus", a nickname so as not to reveal too much about her personal life to Charles.
In season six, Rosa begins dating a cosmetologist named Jocelyn and begins to patch up her relationship with her mother, who was initially disapproving of her bisexuality. In season seven, Rosa and Jocelyn broke up prior to the season's Jimmy Jab Games. In the episode "Valloweaster," she becomes the first three-time Halloween Heist Champion.

In "Stakeout", she received a commendation for her work as the leader of a drug task force.
Terry Jeffords.
Terry Crews portrays Lieutenant (previously Sergeant) Terrence "Terry" Vincent Jeffords, the supervisor of the 9-9's Detective Squad. An avid bodybuilder who stands at more than six feet tall, with a linebacker's build, Terry's intimidating size and appearance is contrasted by his gentle giant persona, being very caring and parental in nature. Jeffords is devoted to his wife and three young daughters, twins Cagney and Lacey, and Ava. He fears the danger of police work because of the possibility that he could leave his children fatherless. Following a panic attack prior to the show's beginning, Terry was removed from field work, but he has since cautiously returned. He is high-strung, prone to nervous excitement, loves yogurt, and has a tendency to refer to himself in the third person. He is an effective and caring leader to the detective squad, often having to play the mature adult in order to keep them in line.
A running gag throughout the series is for Terry to break things (examples include a Magic 8 Ball, a phone and Captain Holt's office) because of his incredible strength. He has been a detective since 1995 and used to be assigned to the 65th Precinct (as seen in "Terry Kitties"), where he was constantly mocked for a botched case which he and Jake later proved he was correct in. In the pilot, Holt mentions that he and Terry have worked together in the 18th Precinct years prior. In 2005, he was the senior detective at the 9-9 (the position Jake now holds since Terry's promotion). He was a linebacker at Syracuse University, where he graduated "magna cum laude", as revealed in "The Swedes". He also studied abroad in Japan while in college and dated a Japanese student named Chiaki who broke his heart. He speaks Japanese infrequently throughout the show.
In season two, Terry nearly gets a vasectomy at his wife's request, but Jake convinces him not to when he finds out Terry secretly wants to have more kids. His wife becomes pregnant later in the season and gives birth to their third daughter, Ava, in season three; Terry names Jake as Ava's godfather.
While Terry was satisfied with his role as Sergeant, he aimed to become a Lieutenant during the first six seasons. As revealed in "The Honeypot", he brought a new pair of suspenders that he planned to put on after he passed the Lieutenant's Exam but kept them in the box when he ended up failing and held onto them as a reminder of his higher goals. In "Moo Moo", he attempted to apply to be a city council liaison to take on more responsibilities but was rejected after reporting that another cop racially profiled him. In season six, Terry revealed to the group that he passed the Lieutenant's Exam weeks before the annual Halloween Heist (which they hosted on Cinco de Mayo).

Amy Santiago.
Melissa Fumero portrays Sergeant (previously Detective) Amy Santiago, Jake's uptight, by-the-book, rule-following Cuban-American partner, and later girlfriend and wife. A self-acknowledged type A personality and neurotic overachiever, she continually tried to ingratiate herself with Captain Holt, and any authority figure in arm's reach of her. In the pilot, Terry cites Amy's competitiveness to Holt as a result of her having seven brothers. Amy is a stickler for department protocol and is frequently exasperated by Jake's childishness, as well as the ease with which he succeeds as a detective. She is initially seen as Holt's teacher's pet, but over time is shown to command respect from others.
Amy was originally a patrol officer at the 64th precinct but requested a transfer to the 99th when her captain almost sexually assaulted her shortly after her promotion to detective. She didn't tell anyone for years out of fear for what it would do to her career, until she revealed it to Jake when they were investigating a sexual assault case in "He Said, She Said".
In the season one finale, Jake confesses that he wishes something romantic could happen between them. She admitted to having feelings for Jake in "The Road Trip", which instigates issues in her relationship with Teddy Wells. Amy was shown to still have feelings for Jake in "Det. Dave Majors". The two share their first kiss in Johnny and Dora and begin dating in New Captain, although their working relationship does not change at all. They decide to move in together in the season three finale "Greg and Larry", but do not do so until season four's "The Fugitive". Jake proposes to Amy at the end of their annual Halloween heist in "HalloVeen" and the two eventually marry in "Jake & Amy". In season 7, Amy becomes pregnant with Jake's child and gives birth to their son, McClane 'Mac' Peralta in the season finale.
Near the end of season three, Amy goes undercover as a pregnant inmate in a women's prison in Texas to obtain information from Maura Figgis. This was done to cover Melissa Fumero's actual pregnancy at the time without making her character pregnant. Amy's actual pregnancy in season seven occurred when Fumero was pregnant with her second child.
After some uncertainty in taking the Sergeant's Exam as depicted in "Chasing Amy", she passes the exam and begins wearing her Sergeant's uniform as well as commanding her own uniformed officers in "NutriBoom".
In season six's "Casecation", she was revealed to be 36 years old. In "The Golden Child", it is revealed that Amy has a relatively strained relationship with her brother and fellow NYPD Lieutenant David Santiago, and she later chides her mother for glorifying David's accomplishments over Amy's. Amy enjoys solving crosswords and attending trivia sessions, generally at Jake's expense, who often embarrasses himself when attempting to participate or becomes awkwardly excluded in conversation.

Charles Boyle.
Joe Lo Truglio portrays Detective Charles Boyle, a nervous and clumsy but honest and hard-working detective. He is Jake's best friend, and almost completely idolizes him. He is divorced from his wife Eleanor, who had numerous affairs during their marriage, to the point where she has to pay alimony to him. He is also a huge, unapologetic foodie, maintaining a weekly Brooklyn pizza-ranking email and often relishing bizarre foreign cuisine that disgusts his coworkers. 
For saving Detective Diaz's life during "Christmas" (during which he was shot in the buttocks), he was awarded the NYPD Medal for Valor in "The Bet", though he was overshadowed by a revered and heroic NYPD horse named Sergeant Peanut Butter. He continues to have a one-sided rivalry with Sergeant (later Lieutenant) Peanut Butter until he seeks his help in getting Jake to the precinct in the season 7 finale. In "The Swedes", it is revealed that Boyle is a graduate of Sarah Lawrence College.
In the show's first season, Charles has a huge crush on Rosa, but he eventually got over her when he starts dating Vivian Ludley, whom he met at Captain Holt's birthday party. They get engaged but break up after Charles refuses to move to Canada with her. He and Gina start seeing each other in season two, and their brief relationship results in the marriage of his father and Gina's mother. In season three, he starts dating Genevieve Mirren-Carter after he and Jake clear her name from an art thief. They eventually move in together and adopt a son from Latvia named Nikolaj. 
In season five, Charles starts his own food truck business called "The One Thing", which specializes in meatball subs. The truck is burned down by one of Charles' former employees, but he is thankful it happened as running the food truck made him spend less time with his family and he also built up a large debt.
Charles has a habit of saying things that he does not realize are overtly sexual or otherwise inappropriate, and rarely realizes it, despite the rest of the squad's disgust.

Gina Linetti.
Chelsea Peretti portrays Regina "Gina" Linetti, the 99th Precinct's sardonic and egomaniacal civilian administrator and Captain Holt's assistant. Despite maintaining a clueless and dimwitted disposition most of the time, she can be surprisingly observant and often demonstrates signs of being more intelligent than she likes to show. Gina is obsessed with social media and is constantly on her phone. It is a running gag to try to pry her from her phone, to the point where Captain Holt becomes involved. She is extremely narcissistic and constantly praises and exalts herself, such as claiming to be a better dancer than Britney Spears in the episode "Karen Peralta". As the only civilian in the precinct, Gina often uses her outsider's perspective to assist the other detectives. In "The Party", to prevent the mostly working class detectives from embarrassing themselves in front of a crowd of academics, Rosa tricks Gina into talking to a group of psychology professors at Holt's birthday party, who then take copious notes about her narcissistic personality. They conclude that she has a complete overlap of ego and id, a condition previously thought to be purely theoretical.
She casually admits on myriad occasions that she doesn't value her colleagues – except for Jake – as people. She was also childhood friends with Jake, who got her the job at the precinct. Gina also ruined Jake's senior year of high school by framing him as "The Tattler", though she did it to avoid Jake getting involved with the wrong crowd. She transfers to the Public relations Division with Captain Holt in "Johnny and Dora", and returns to the 9-9 with him in "The Oolong Slayer". In the episode "The Apartment", it is revealed that she has been engaged eight times, but never married. In "The Fugitive Pt. 2", she declares that Charles' texts are so strange that she would rather get hit by a bus than receive another one from him. At the end of the episode, she receives Charles' first unchecked, quality text for her, but while congratulating him, she ironically does indeed get hit by a bus. The penultimate episode of season four reveals she has become pregnant following a relationship with Charles' cousin, Milton (which coincided with Chelsea Peretti's actual pregnancy). She is absent for the first half of season five on maternity leave after giving birth to a girl she nicknames "Iggy" (short for Enigma). 
In the episode "Halloween IV", Gina reveals that in the fourth grade at a classmate's birthday party, a bowling ball fell onto her face. This incident knocked out her two front teeth; she has been wearing false teeth since.
In season six, Jake helps Gina realize that her talents would be better spent elsewhere and she quits her job. She becomes an internet celebrity and hosts a web show called "The G-Hive," in which she gives her viewers life advice. Her work has made her too busy to spend time with her former coworkers, but she is aiming to improve after Jake confronts her for not talking to them for months. 
Raymond Holt.
Andre Braugher portrays Captain Raymond Jacob Holt, the 99th Precinct's strict Commanding Officer. Holt is known for his cold, calm and robotic manner of speaking, overly formal demeanor and lack of outwardly visible emotion, although his non-work friends frequently refer to him having a much more fun persona that is very rarely seen by either the Nine-Nine members or the viewer. He has sophisticated and cultured interests, enjoying classical music, opera and attending dinner parties with his husband's academic friends, amongst other things. The Nine-Nine is Holt's first command despite many years of outstanding service, and he attributes the delay to prejudice against both his race and homosexuality. He came out in 1987 and until recently led a group that supported LGBT African-American NYPD members, which he himself created. He was a homicide detective in the 1980s, and spent twelve years in the Community Affairs Bureau immediately prior to commanding the Nine-Nine.
Holt is married to Kevin Cozner, the Chair of Columbia University's Classics Department, and has a longstanding professional rivalry with Madeline Wuntch, with whom he came up through the ranks. The two were once friends, but their friendship soured after Holt rejected Wuntch's sexual advances on account of his homosexuality; while his career stalled, she kept advancing and is now his immediate superior. After he and Peralta successfully solve a major case in "The Chopper", Bureau Chief Wuntch nominates him for a promotion to head of the NYPD Public Affairs Division, a promotion he accepts lest Wuntch transfer his staff to horrible posts around New York City. During the number of weeks Holt was in charge of Public Affairs, he was unable to accomplish anything significant thanks to Chief Wuntch's constant micromanaging. After helping Peralta solve a serial killer case, Holt finds himself transferred back to command of the 9-9 by the Chief of Brooklyn Detectives. He owned a burgundy Chevrolet Corvair named Gertie which was his prized possession until it was stolen in "The Fugitive". Doug Judy purchases him a new identical one and names it Sexarella.
At the end of season three, Jake and Holt are forced to go into witness protection in Florida when they are threatened by crime boss Jimmy "The Butcher" Figgis. He works at a family entertainment center called the Fun Zone under the alias 'Greg Stickler' until he and Jake bait Figgis into coming to Florida and taking the criminal down with the Nine-Nine. In season five, his life and career are put at risk when he makes a deal with mobster Seamus Murphy in exchange for information to clear Jake and Rosa's names from Lt. Hawkins.
Later in season five, Holt learns that the New York City Police Commissioner is retiring at the end of the year and that he is on the shortlist of candidates to replace him. He spends the rest of the season campaigning to win the Commissioner title, but ends up losing to John Kelly.
In season six, Holt is encouraged by Jake and Amy to stand up to Kelly's regressive policies, leading the Commissioner to retaliate against the Nine-Nine. However, Peralta and Wuntch team up, without Holt's knowledge, to take Kelly down, resulting in Wuntch being named interim Commissioner. This detente becomes short-lived as Holt is demoted to a uniformed officer by Commissioner Wuntch after she realizes he was promoted to detective too soon earlier in his career. Shortly after Wuntch's death, however, he is quickly promoted back to captain in the middle of the seventh season.

In "Stakeout", he received a commendation for his supervision of Det. Diaz's drug task force.
Michael Hitchcock.
Dirk Blocker portrays Detective 3rd Grade Michael Hitchcock (season 2–present; recurring season 1), an enthusiastic but clueless detective who has been best friends and partners with Detective Scully for over 30 years. Despite their inept nature, Hitchcock and Scully have both shown on occasion to be competent and even good detectives, though their laziness tends to keep them from demonstrating this most of the time. As revealed in "Hitchcock and Scully", the two were excellent detectives in their youths and had well-built bodies, but their careers and their physiques went downhill after they tried the wings at their eventual favorite restaurant, Wing Slutz. Unlike most police detectives, Hitchcock and Scully are more than happy to do paperwork rather than expend any energy in the field.
The majority of the precinct tends to be disgusted by Hitchcock's more perverted nature and attitude towards women. It is revealed in "The Last Ride" (Season 4) that Hitchcock held the all-time record for closed cases at the 99th Precinct, one more than Sgt. Jeffords as of that episode. This is mainly due to Hitchcock being at the 99th twenty years longer than Terry. To celebrate, Hitchcock got a tattoo of himself holding a gun and putting it in his mouth, oblivious to what it actually implies.

Norm Scully.
Joel McKinnon Miller portrays Detective Norman "Norm" Scully (season 2–present; recurring season 1), a middle-aged, lazy desk worker who has been best friends and partners with Detective Hitchcock for over 30 years. Scully shows talent as a tenor opera singer and French speaker, has an understanding of Morse code and can "make great coffee", according to Sgt. Jeffords. He also displays an uncanny ability to reassemble shredded documents in one episode. Scully routinely discloses disgusting medical issues like the entire bottom of his foot being a wart or having various strains of fungi. He claims to constantly have medical emergencies, and despite having a pacemaker fitted, he frequently suffers from heart attacks. He often embarrasses himself either unintentionally or willingly and admits to being indifferent to the judgment of others (most frequently, the fellow members of his squad.) In the early seasons, Scully is married and has a dog. The team are unsure which one of them is called Kelly, though it is later revealed in season 7 that both of them had this name. After his wife leaves him, he begins dating a woman named Cindy Shatz, who is very similar to him in her attire and personality. He has a twin brother named Earl, also portrayed by Miller.
