The 1976 Australian Touring Car Championship was a CAMS sanctioned Australian motor racing title for Group C Touring Cars. It was the 17th running of the Australian Touring Car Championship. The championship began at Symmons Plains Raceway on 29 February and ended at the Phillip Island Grand Prix Circuit on 28 November in the longest season in the history of the series. 1976 saw a substantial change to the ATCC calendar which was expanded to eleven rounds, incorporating the end-of-season long distance Australian Championship of Makes races for the first time. These races included Sandown's Hang Ten 400 and the Phillip Island 500K, although notably not the Bathurst 1000.
