The twenty-fifth season of Saturday Night Live, an American sketch comedy series, originally aired in the United States on NBC between October 2, 1999, and May 20, 2000. The entire cast from last season returned for another year. Jimmy Fallon, Chris Parnell and Horatio Sanz were all promoted to repertory status, with the cast otherwise unchanged at the start of the season. As the season progressed, the show added two new cast members. Rachel Dratch, recruited from Chicago's The Second City, where she was head writer Tina Fey's comedy partner, joined the show in the episode hosted by Norm Macdonald. Towards the end of the season, Maya Rudolph of The Groundlings joined the show, starting with the episode hosted by John Goodman.
