Season Description The 2021 FIA Formula 2 Championship was a motor racing championship for Formula 2 cars that was sanctioned by the Fédération Internationale de l'Automobile (FIA). The championship was the fifty-fifth season of Formula 2 racing and the fifth season run under the FIA Formula 2 Championship moniker. It was an open-wheel racing category that served as the second tier of formula racing in the FIA Global Pathway. The category was run in support of selected rounds of the 2021 FIA Formula One World Championship. As the championship was a spec series, all teams and drivers competing in the championship ran the same car, the Dallara F2 2018. The championship was contested over twenty-four races at eight circuits. It began in March 2021 with a round in support of the Bahrain Grand Prix, and ended in December where it supported the Abu Dhabi Grand Prix.
Mick Schumacher was the defending drivers champion having secured the title at the final race of the 2020 season at the Bahrain International Circuit. Schumacher was promoted to Formula One with Haas for the 2021 F1 season. Schumacher's team Prema Racing entered the season as the defending teams champions having also secured their title at the final race of the 2020 season at Bahrain.
A new chassis package was due to be introduced for the 2021 season, but in a bid to cut costs in light of the COVID-19 pandemic, the lifespan of the Dallara F2 2018 chassis package was extended until 2023.
