The 2026 FIA Formula One World Championship is a motor racing championship for Formula One cars and the 77th running of the Formula One World Championship. It is recognised by the Fédération Internationale de l'Automobile (FIA), the governing body of international motorsport, as the highest class of competition for open-wheel racing cars.

Honda, through its Honda Racing Corporation subsidiary, entered into an exclusive works team agreement with Aston Martin, and are supplying them with their own power unit after ending its relationship with Red Bull Racing. Ford returned to the sport for the first time since , supporting Red Bull Powertrains in supplying power units to Red Bull Racing and Racing Bulls. Renault is no longer an engine supplier as Alpine switched to Mercedes power units.
Each team is required to enter at least two drivers, one for each of the two mandatory cars. All teams compete with tyres supplied by Pirelli.
