The 2016 CAMS Australian GT Championship was a CAMS-sanctioned Australian motor racing championship open to FIA GT3 cars. It was the 20th running of the Australian GT Championship. The championship began on 3 March 2016 at the Adelaide Street Circuit and ended on 13 November at Highlands Motorsport Park, with five rounds held in Australia and one round in New Zealand.

The Australian GT Championship is a CAMS-sanctioned national title for drivers of GT cars, held annually from 1960 to 1963, from 1982 to 1985 and from 2005. Each championship up to and including the 1963 title was contested over a single race and those after that year over a series of races. The categories which have contested the championship have not always been well defined and often have become a home for cars orphaned by category collapse or a sudden change in regulation.
