The FIA Formula 3 Championship is a third-tier international single-seater racing championship and organised by the Fédération Internationale de l'Automobile (FIA). The championship launched in 2019 as a feeder series for the FIA Formula 1 World Championship and FIA Formula 2 Championships. It was the result of a merger between two third-tier single-seater racing championships, the GP3 Series and the FIA Formula 3 European Championship as it was announced on 10 March 2018. The championship is part of the FIA Global Pathway consolidation project plan. Unlike its predecessor, the Formula 3 European Championship, the series runs exclusively in support of Formula One races.
