"Welcome to Los Santos" is the theme song and introductory music for Grand Theft Auto V.


It is composed by Oh No, who was commissioned in 2013 by Rockstar Games to compose and produce the theme song for Grand Theft Auto V. Although the song was originally released as a standalone introductory theme, the song later appeared on the in-game radio station, The Lab, mixed by MC Eiht and Freddie Gibbs. The music also later appeared as a full-length track on the Welcome to Los Santos album released by Oh No and various other related artists working in collaboration for Rockstar Games, which also featured a variety of songs from The Lab.

This song is one of only four main theme songs to be released officially, along with "Theme from Vice City", "Theme from San Andreas" and "Soviet Connection".
