The ADAC GT Masters is a grand tourer-based auto racing series founded by the international Stéphane Ratel Organisation (SRO) and supported by the German ADAC automotive club.

The original ADAC GT Cup was created in 1993, as a national grand tourer championship similar to the Deutsche Tourenwagen Meisterschaft (DTM).

The ADAC GT Masters uses a similar formula to the one used in the FIA GT3 European Championship, also created by the SRO.

Vehicles that ran in the 2019 championship include Porsche 911 GT3 R, Audi R8 LMS GT3 Evo, Ferrari 488 GT3, Corvette C7 GT3-R, BMW M6 GT3, Lamborghini Huracan GT3, Mercedes-AMG GT3, Aston Martin Vantage GT3, Honda NSX GT3 EVO.

The current driver champions are Elias Seppänen and Tom Kalender in the No 1 Mercedes-AMG GT3.
