The 1962 Australian GT Championship was a CAMS sanctioned motor racing title for drivers of Appendix K GT cars. The title, which was the third Australian GT Championship, was contested over a single race held at the Lakeside circuit, in Queensland, Australia on 8 July 1962.

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.
