1999 FIA GT Championship

Olivier Beretta of Monaco won his second consecutive FIA GT Drivers' Championship in 1999

The 1999 FIA GT Championship was the third season of FIA GT Championship, an auto racing series endorsed by the Fédération Internationale de l'Automobile (FIA) and organized by the Stéphane Ratel Organisation (SRO). The races featured grand touring cars and awarded a drivers and teams championship. The season began on 11 April 1999 and ended 26 November 1999 after ten races in Europe, the United States, and China.

Following the domination of Mercedes-Benz the previous two seasons, pre-season entries for the GT1 category were so few that the FIA and SRO chose to eliminate the class for 1999. The former GT2 class became the sole category of cars eligible for the championships, although cars from national championships were allowed to participate on an invitational basis at some events. Chrysler Viper Team Oreca dominated the championship for the entire season, winning all but one race en route to the Teams title. Olivier Beretta won his second-consecutive championship, sharing the Drivers title with teammate Karl Wendlinger, earning six of Oreca's nine race victories.
