The championship was the fifty-fourth season of Formula 2 racing and the fourth season run under the FIA Formula 2 Championship moniker. It is an open-wheel racing category, that serves as the second tier of formula racing in the FIA Global Pathway. The category was run in support of selected rounds of the 2020 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.
