The Los Santos Forum is the main stadium servicing Los Santos, and is located at the southeast end of the city, in the border of East Beach and Playa del Seville. It resembles a miniature version of the Great Western Forum (also known as the Los Angeles Forum) in the city of Inglewood, the city which Idlewood was based on. However, the Forum is located in East Beach which is based on Long Beach and it is unknown why it would be located there instead of Idlewood.From 1967-1999 the Great Western Forum was home to the Los Angeles Lakers and the Los Angeles Kings. This would imply that the Los Santos Forum may be home to the professional sports teams in Los Santos such as the Los Santos Dribblers and the Los Santos Slappers.
This is the location for a stadium race called 8-Track, since the track inside the stadium is shaped like the number 8. A Monster and a Hotring Racer will spawn near the entrance when that race is passed. The stadium is unique for having a jumbo TV showing camera fly-bys around the stadium.
It is more than likely that the Los Santos Saints play there.
