A fictionalized version of the state of California in the Grand Theft Auto/ GTA video/computer games. Named after the San Andreas Fault. Originally San Andreas was only a city in the original Grand Theft Auto game from 1997 and was the second city you were able to play in. However for the next game Rockstar has made San Andreas into an entire state consisting of three major cities(Los Santos, San Fierro, and Las Venturas) with various small backwater towns and countryside scattered in-between the major cities.
"San Andreas was one of the three cities in the original GTA."
"San Andreas is going to own when it gets released!"
"He moved from Florida and now lives in San Andreas."
