The SoCal USRA (Southern California United Slot Racers Association) is an organisation dedicated to slot car racing in Southern California. It organizes a yearly championship contested at various slot car tracks around Southern California and also currently includes races in Las Vegas.

Racing is conducted over a number of classes with two major divisions. The Wing division is for "Wing" cars, while the Scale division racing is for the more "Scale" cars. Classes in the wing division 1 include Spray Glue Boxstock, Group 12, C12, Group 27, One Motor Group 7 and Group 7. Classes in the scale division include 4" Nascar, 4.5" Nascar, GT1 and GT12. Within the scale division racing there are separate championships for "Amatuer", "Advanced"  and "Expert" racers.

Included in both the Wing and Scale championships is the prestigious Western States Championship. This race, although part of the championship, is the major race each year in Southern California and was first raced way back in 1968.
