In relation to Australian motorsport, Group C refers to either of two sets of regulations devised by the Confederation of Australian Motor Sport (CAMS) for use in Australian Touring Car Racing from 1965 to 1984. These are not to be confused with the FIA's Group C sports car regulations, used from 1982 to 1992 for the World Endurance Championship / World Sports-Prototype Championship / World Sportscar Championship and the 24 Hours of Le Mans.
