The Mets retired Seaver's uniform number 41 in 1988 in a Tom Seaver Day ceremony, making him the franchise's first player to be so honored.

Seaver was elected to the Baseball Hall of Fame on January 7, 1992, with the then highest percentage of votes with 98.84%.
He was named on 425 out of 430 ballots.
Three of the five ballots that had omitted Seaver were blank, cast by writers protesting the Hall's decision to make Pete Rose ineligible for consideration.
One ballot was sent by a writer who was recovering from open-heart surgery and failed to notice Seaver's name.
The fifth "no" vote was cast by a writer who said he never voted for any player in their first year of eligibility.
Seaver is one of two players enshrined in the Hall of Fame with a Mets cap on his plaque, along with Mike Piazza.
He was also inducted into the New York Mets Hall of Fame in 1988, the Marine Corps Sports Hall of Fame in 2003, and the Cincinnati Reds Hall of Fame in 2006.

In 1999, Seaver ranked 32nd on The Sporting News' list of the 100 Greatest Baseball Players, the only player to have spent a majority of his career with the Mets to make the list.
That year, he was also a nominee for the Major League Baseball All-Century Team.
Baseball purists often compare him to Christy Mathewson for his combination of raw power, pinpoint control, intelligence, and intense scrutiny of his performance.
Seaver was the foremost latter-day exponent of the "drop and drive" overhand delivery that utilized his powerful legs, took strain off his arm, and helped ensure his longevity.
He always credited the training he received in the Mets' organization, citing the long careers of teammates Jerry Koosman, Nolan Ryan and Tug McGraw as further proof.
Seaver could also help himself at the plate.
A decent hitter and proficient bunter, Seaver hit 12 home runs during his career, along with a relatively solid lifetime average for a pitcher of .154.

Hank Aaron stated that Seaver was the toughest pitcher he ever faced.
 Seaver approached Aaron before his first All-Star Game in 1967 and asked Aaron for his autograph.
Seaver felt the need to introduce himself to Aaron, as he was certain "Hammerin' Hank" would not know who he was.
Aaron replied to Seaver, "Kid, I know who you are, and before your career is over, I guarantee you everyone in this stadium will, too."

On September 28, 2006, Seaver was chosen as the "Hometown Hero" for the Mets franchise by ESPN.
Seaver made a return to Shea Stadium during the "Shea Goodbye" closing ceremony on September 28, 2008, where he threw out the final pitch in the history of the stadium to Piazza.
He and Piazza then opened the Mets' new home, Citi Field, with the ceremonial first pitch on April 13, 2009.

The 2013 Major League Baseball All-Star Game was dedicated to Seaver.
 He concluded the introduction of the starting lineup ceremonies by throwing out the ceremonial first pitch.
Mets player David Wright participated.

In 2019, the Mets renamed the street outside of Citi Field stadium to 41 Seaver Way in his honor.
