2024 FIA Formula 3 Championship

The 2024 FIA Formula 3 Championship was a motor racing championship for Formula 3 cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The championship was the fifteenth season of Formula 3 racing and the sixth season run under the FIA Formula 3 Championship moniker. It was an open-wheel racing category serving as the third tier of formula racing in the FIA Global Pathway. The category was run in support of selected rounds of the 2024 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 F3 2019.

Leonardo Fornaroli won the championship in his second year with Trident, yet did not take a single race victory throughout the season, becoming the first winless champion in FIA Formula 3 history. Prema Racing entered the championship as the reigning Teams' Champions, having secured their title at the final race of the 2023 season in Monza. They also secured the Teams' Championship title in 2024.

2024 was the final year using the Dallara F3 2019 chassis, which debuted in the inaugural 2019 season. Starting in 2025, a new chassis was introduced, the Dallara F3 2025.

The following teams and drivers were competing in the 2024 FIA Formula 3 Championship. As the championship was a spec series, all teams competed with an identical Dallara F3 2019 chassis with a 3.4 L (207 cu in) naturally-aspirated V6 engine developed by Mecachrome. All teams competed with tyres supplied by Pirelli.

PHM Racing now operated independently of Charouz Racing System, after the latter co-ran the team during the 2023 season. Ahead of the season, PHM also announced the AIX Investment Group as a new title sponsor, changing the team's name to PHM AIX Racing.

After Rodin Cars became Carlin's majority shareholder in 2023 and rebranded it as Rodin Carlin, the Carlin family departed the team, with Rodin taking full ownership and renaming the team Rodin Motorsport.

The AIX Investment Group completed its acquisition of PHM Racing ahead of the third round of the season and rebranded the team to AIX Racing.

Reigning Teams' Champions Prema Racing saw two of their drivers graduate to Formula 2, with Zak O'Sullivan joining ART Grand Prix and Paul Aron signing with Hitech Pulse-Eight. Their replacements were Gabriele Minì, leaving Hitech Pulse-Eight after finishing seventh in his debut season, and Red Bull junior Arvid Lindblad, graduated from the team's Italian F4 outfit after coming third in 2023.
