The 2021 Le Castellet Formula 3 round was the 2nd round of the 2021 FIA Formula 3 Championship. It took place at the Circuit Paul Ricard and ran from 18 to 20 June, featuring 3 races in support of the 2021 French Grand Prix.
FIA Formula 3 last raced here in 2019. It was taken off in 2020 in favor of the Circuit Zandvoort. However, changes to the calendar due to the COVID-19 pandemic and a new cost-cutting measure meant that it returned for 2021. László Tóth tested positive for COVID before the weekend, and he was replaced by Pierre-Louis Chovet, who had been replaced at Jenzer by Johnathan Hoggard for sponsorship reasons.[1] The round was originally scheduled to run from 25 to 27 June, but was rescheduled due to Formula One changing their calendar.[2]
The Qualifying session took place on 18 June 2021, with Frederik Vesti besting Dennis Hauger to take his first pole position of the season.
