After spending several years as a coach in the Dodgers' organization, Scioscia was hired by new Angels general manager Bill Stoneman to be the Angels' manager after the 1999 season, following the late-season resignation of Terry Collins and interim managerial tenure of Joe Maddon.
Scioscia would retain Maddon as an assistant until Maddon received his own managerial position with the Tampa Bay Devil Rays in 2006.

Under the leadership of Stoneman and Scioscia, the Angels ended their 16-year playoff drought in 2002, winning the AL Wild Card and ultimately winning the franchise's first World Series, a series that pitted the Angels against a San Francisco Giants team managed by Scioscia's former Dodgers teammate Dusty Baker.
In winning the series, Scioscia became the 17th person to win a World Series as both a player and a manager (not including those who won as a player-manager).

Scioscia was honored as 2002 American League Manager of Year by the Baseball Writers' Association of America (the official Manager of the Year award, as recognized by Major League Baseball).
 He was also named 2002 A.L. Manager of the Year by The Sporting News, USA Today Sports Weekly, and the Negro Leagues Baseball Museum.
 He was further named the overall Major League 2002 Manager of the Year by Baseball America.

The Angels under Scioscia would go on to enjoy a period of on-field success never before seen in franchise history, winning five American League West division titles in six years (surpassing the number won by all previous Angels managers combined).
Scioscia's Angels broke the franchise single-season win record with 99 wins in 2002, and again with 100 wins in 2008.
However, they have yet to win another American League pennant or World Series since their memorable 2002 run.

Scioscia is the Angels' all-time leader in wins and games managed, surpassing original manager Bill Rigney's totals in both categories in 2007 and 2008, respectively.
He was also the longest tenured manager in Major League Baseball.
In January 2009, he received a multi-year extension on his contract; his former contract ran through the 2010 season.
The number of additional years created through this contract was 10 years, through 2018.
Scioscia was honored as 2009 American League Major League Manager of Year by the Baseball Writers' Association of America (the official Manager of the Year award, as recognized by Major League Baseball).

Scioscia became the first manager to reach the playoffs in six of his first ten seasons.
On May 8, 2011, the Angels defeated the Cleveland Indians, which marked Scioscia's 1,000th win as a major league manager.

A rift developed between Scioscia and Jerry Dipoto, the Angels' general manager, when Dipoto fired Mickey Hatcher from the role of the team's hitting coach in 2012.
Despite rumors that the Angels might replace either Dipoto or Scioscia after the 2013 season, Moreno announced that both would return to the Angels for the 2014 season.

Tension between Dipoto and Scioscia continued during the 2015 season regarding the way Scioscia and his coaches delivered statistical reports developed by Dipoto and the front office to their players.
Dipoto resigned his post on July 1, 2015, despite efforts from the Angels to convince him to stay.
Former Angels general manager Bill Stoneman, who hired Scioscia before the 2000 season, was hired as the interim GM.

After 19 seasons as manager, following the conclusion of the 2018 season, Scioscia announced that he would step down as manager of the Angels on September 30, 2018.
He finished with a record of 1650 wins and 1428 losses.
