The 1993 Camel GT Championship and Exxon Supreme GT Championship seasons were the 23rd season of the IMSA GT Championship auto racing series. It was the final year of the Camel's sponsorship of the prototype class, and the final year of the GTP and GTP Lights prototype categories before they were replaced with the World Sports Car (WSC) class of prototypes the following year.
