The 2009 FIA GT Championship season was the thirteenth and final season of the FIA GT Championship for grand tourer cars competing in the GT1 and GT2 categories. The season began 3 May, and ended 25 October after eight races. This was also the final season of a combined GT1 and GT2 championship before the launch of the FIA GT1 World Championship in 2010.

The FIA GT Championship was a sports car racing series organized by the Stéphane Ratel Organisation (SRO) at the behest of the Fédération Internationale de l'Automobile (FIA). The championship was mostly concentrated in Europe, but throughout the years has visited other continents including Asia and South America. At the end of 2009, the championship was replaced by the FIA GT1 World Championship, which morphed into the FIA GT Series for 2013.
