The 2025 FIA Formula 3 Championship is a motor racing championship for Formula 3 cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The championship is the sixteenth season of Formula 3 racing and the seventh season run under the FIA Formula 3 Championship moniker. FIA Formula 3 is an open-wheel racing category serving as the third tier of formula racing in the FIA Global Pathway. The category is run in support of selected rounds of the 2025 FIA Formula One World Championship. As the championship is a spec series, all teams and drivers competing in the championship run the same car, the Dallara F3 2025.
Prema Racing entered the season as the reigning Teams' Champions, having secured their title at the penultimate race of the 2024 season at Circuit de Spa-Francorchamps.
2025 saw the introduction of a new Dallara-built chassis, with the championship retiring the Dallara F3 2019 it had used since its inaugural season in 2019.
