The twenty-fourth season of Saturday Night Live, an American sketch comedy series, originally aired in the United States on NBC between September 26, 1998, and May 15, 1999.
Before the start of the season, Jim Breuer, who had been a cast member for three seasons since 1995, left the show at the request of head writer Adam McKay. Following Breuer's departure, the show added three new featured players: stand-up comedian Jimmy Fallon, Chris Parnell, a performer with The Groundlings in Los Angeles, and Upright Citizens Brigade and Second City performer Horatio Sanz.
Starting with this season, every new cast member is hired as a featured player before being promoted to Repertory; additionally, all featured players are credited for every episode, whether they appear or not.
Fallon, Parnell, and Sanz were all also promoted to repertory status during the following season.
Following the finale, no changes were made to the cast, and everyone returned for the next season.
