The 2027 FIA Formula One World Championship is a planned motor racing championship for Formula One cars which will be the 78th 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. The championship is scheduled to be contested over twenty-four Grands Prix held around the world. Drivers and teams are set to compete for the titles of World Drivers' Champion and World Constructors' Champion, respectively.
The following constructors and drivers are under contract to compete in the 2027 World Championship. All teams are due to compete with tyres supplied by Pirelli. Each team is required to enter at least two drivers, one for each of the two mandatory cars.

Esteban Ocon is set to depart Haas at the end of the 2026 season after two seasons. He is set to be replaced by Rafael Câmara, graduating from Formula 2.

The 2027 calendar is scheduled to comprise twenty-four Grands Prix. The Bahrain, Australian, Japanese, Canadian, Monaco, British, Italian, São Paulo, Qatar, and Abu Dhabi Grands Prix will feature the sprint format.
The Dutch Grand Prix will not be held in 2027, as the organisers announced that the 2026 edition would be the final running of the Grand Prix. The Portuguese and Turkish Grands Prix will return to the calendar for the first time since 2021. The Barcelona-Catalunya Grand Prix will be absent from the 2027 calendar and will be held in 2028, 2030 and 2032 as part of a rotation agreement with the Belgian Grand Prix, which will be held in 2027, 2029 and 2031. The Bahrain Grand Prix is set to return to the Bahrain International Circuit after its 2026 edition was relocated to the Sepang International Circuit in Malaysia due to the 2026 Iran war, while the Saudi Arabian Grand Prix is scheduled to return after its 2026 edition was cancelled.
The engine regulations introduced in 2026 will be amended to increase internal combustion engine power from 400kW to 420kW while reducing maximum electrical power deployment in the MGU-K from 350kW to 300kW. This changes the ratio of power from 53:47 to 58:42, before changing to 60:40 in 2028. As a result, fuel flow will increase 5%, which in turn has required overall race distance to be shortened from 305 km (190 mi) to 290 km (180 mi) to allow teams to continue to use elements of their 2026 chassis designs which can include the fuel tank. Harvesting will be increased from 350kW to 375kW. Together, these regulation changes are intended to reduce electrical energy exhaustion and decrease the need for lift-and-coast or 'super clipping' on long straights.
In addition to engine changes, gearbox homologation will also be scrapped starting in 2027, allowing teams to alter their design in-season as they see fit.
Due to changes to the fuel flow regulations for 2027, every single race except for the Monaco Grand Prix will now have a distance of 290 km (180 mi) instead of 305 km (190 mi), reducing races by two or three laps. The FIA has confirmed this change will persist for just for one season, and races will return to full distance in 2028.
The FIA will gain more flexibility in extending free practice sessions in case of interruptions. Additionally, the three hour clock which was used to determine the length of a race when including stoppages has been scrapped and will be replaced by a hard stop time for racing activity. The two hour race limit will remain the same.
On 4 September 2026, the second F1 Live event following F1 75 Live in 2025 was announced for 18 February 2027. It will be held in Milan, Italy. A single pre-season test is scheduled to be held at the Bahrain International Circuit in Sakhir on 24–27 February.
