The FIA Formula 3 European Championship was a European Formula Three (F3) auto racing competition, organised by the Fédération Internationale de l'Automobile (FIA). After one season of the FIA Formula 3 International Trophy, the FIA revived the FIA Formula 3 European Championship. The ten-event season included seven Formula 3 Euro Series rounds, two British Formula Three rounds and DTM-supporting round at Brands Hatch. From 2013, the series started running its own rounds, based upon the defunct Formula 3 Euro Series.

In 2019, the series merged with the GP3 Series to form the FIA Formula 3 Championship, and was due to relaunch as the Formula European Masters and run in support of the Deutsche Tourenwagen Masters. The championship was cancelled ahead of its debut season due to lack of competitors. The championship would have used the current spec cars and were working with Dallara to design a new car for 2020, but it was replaced by GT4-based series, DTM Trophy as the successor.
