Championship Off-Road Racing was a sanctioning body for short course off-road racing in the United States. It formed in 1998 and went bankrupt in 2008. Its Midwest races were supplanted in 2007 by the Traxxas TORC Series and by the Lucas Oil Off Road Racing Series on the West Coast in 2009. Both received most of the drivers and adopted the same racing format.

The Lucas Oil Off Road Racing Series, also known as LOORRS, was a short course off-road racing series in the United States and also in Mexico beginning in 2015. The series featured events in Arizona, California, Nevada, Missouri and hosted a weekend of racing in Ensenada, Mexico at Baja International Short Course near Estero Beach. The title sponsor for the series was Lucas Oil Products, whom also owned, sanctioned, and operated the series. It effectively replaced the CORR series starting in 2009.
