The USAFL Western Regionals is a representative Australian rules football tournament of USAFL clubs based in the western regions of the United States.
It is a two-part series established after the collapse of the Californian Australian Football League in 2004 to give clubs without regular league play (although some participate in the North West Pacific Australian Football League) a chance to compete in preparation for the USAFL National Championships, determining the seedings for the nationals as well as the USAFL East vs West tournament.
Sides that compete or have competed include: The first Western Regionals were held in San Diego on August 14 and 15 of 2004, with the Denver Bulldogs winning the tournament.
The 2005 series round 1 was held in Orange County and round 2 in Denver, again dominated by the Denver Bulldogs.
The 2006 round 1 series was held in San Pedro, with San Diego Lions taking the honors.
