The 2009 FIA GT3 European Championship season was the fourth season of the FIA GT3 European Championship. The season began on 2 May at Silverstone and will end on 14 November 2009 at Zolder. The season featured six double-header rounds, with each race lasting for a duration of 60 minutes. Most of the events were support races to the 2009 FIA GT Championship season, the 2009 GT4 European Cup and the 2009 Lamborghini Super Trofeo.
Phoenix Racing pairing Christopher Haase and Christopher Mies claimed the overall title, with a fourth place in the final race of the season at Zolder. In the Teams Championship, Hexis Racing were champions ahead of Matech Racing and Team Rosberg.
Two new manufacturers join the FIA GT3 category in 2009. Audi, with their V10-powered R8 LMS, and Alpina's B6, based on the 6-Series. The Ford Mustang FR500GT3 does not return in 2009. Ferrari replaces its previous F430 GT3 with the new 430 Scuderia GT3, while Morgan's Aero 8 is replaced by the Aero Super Sport.
Also new for 2009 is an alteration in the structure of teams and manufacturers. Although manufacturers will still be allowed a maximum of six cars, teams are only limited to two cars. There is therefore a maximum of three teams which can campaign a single manufacturer. The manufacturers of Ascari, Dodge, Jaguar, Lamborghini, and Morgan will not be eligible for the Manufacturers Cup due to not supplying the minimum of four cars required to enter the Cup.
