The 1992 Camel GT Championship and Exxon Supreme GT Series seasons were the 22nd season of the IMSA GT Championship auto racing series. It was for GTP and Lights classes of prototypes, as well as Grand Tourer-style racing cars which ran in the GTS, GTO, and GTU classes. It began February 1, 1992, and ended October 11, 1992, after fifteen rounds.
The GT and Prototype classes did not participate in all events, nor did they race together at shorter events. Races marked with All had all classes on track at the same time.
