The 1988 Camel GT Championship season was the 18th 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 GTO and GTU classes. It began January 30, 1988, and ended October 23, 1988, after seventeen rounds.
The GT and Prototype classes did not participate in all events, nor did they race together at shorter events. Races marked as GT featured both GTO and GTU classes combined. Races marked with All had all classes on track at the same time.
The GTP Drivers Championship was won by Australian Geoff Brabham, driving a Nissan GTP ZX-T.
