2021 French F4 Championship

The 2021 French F4 Championship was the 11th season to run under the guise of the French F4 Championship and the fourth under the FIA Formula 4 regulations. The championship used Mygale M14-F4 chassis. The series began on 3 April at Circuit Paul Armagnac and ended on 24 October at Circuit de Nevers Magny-Cours.

Race calendar
On 27 November 2020 French Federation of Automobile Sport announced a seven-round calendar with the round supporting provisionally 2021 French Grand Prix.
