Grand Theft Auto: San Andreas is an open-world, action-adventure video game developed by Rockstar North and published by Rockstar Games. First released on 16 October 2004 for the PlayStation 2, San Andreas has an in-game radio that can tune in to eleven stations playing more than 150 tracks of licensed music, as well as a talk radio station. The songs featured on the radio stations originated in or before the early 1990s, the period in which the game is set.

The game's music has been released on two official soundtracks: Grand Theft Auto: San Andreas Official Soundtrack, released in November 2004, consists of selections from the in-game radio; and Grand Theft Auto: San Andreas Official Soundtrack Box Set, released in December 2004, consists of eight volumes comprising highlights from the game's radio stations.
