2021 Abu Dhabi Grand Prix

The 2021 Abu Dhabi Grand Prix was a Formula One motor race held on 12 December 2021 at the Yas Marina Circuit in Abu Dhabi, United Arab Emirates and the 13th edition of the Abu Dhabi Grand Prix. Contested over 58 laps, it was the twenty-second and final round of the 2021 Formula One World Championship. The race decided both the Drivers' and Constructors' championships; Max Verstappen of the Red Bull Racing team and Lewis Hamilton of the Mercedes-AMG Petronas team both entered the race on 369.5 points, with Verstappen clinching his maiden Drivers' title while Mercedes-AMG Petronas won a record-breaking eighth consecutive Constructors' championship.

Hamilton had led most of the race and appeared on course to win his eighth title. Verstappen overtook Hamilton on the final lap after a controversial safety car restart in the last moments of the race. The ensuing dispute stemmed from race director Michael Masi's handling of the safety car, which was seen by some as inconsistent with usual race procedures and sparked a wide debate on whether it was influenced by the closeness of the championship battle and the spectacle, as well as the human element of the decisions. Mercedes immediately protested the race result, and the race stewards heard the protest and dismissed it. Mercedes had the option to appeal the outcome to the FIA International Court of Appeal, but did not do so.

The FIA, the governing authority of the sport, subsequently conducted an inquiry into the race, confirming the race and the championship results. It concluded that the rules had been ambiguous and the safety car regulations required clarification. The FIA issued a press statement stating that race director Michael Masi had acted "in good faith and to the best of his knowledge given the difficult circumstances". The inquiry lead to a clarification of the safety car regulations, communications between the teams and race control were limited, and the role of the race director was restructured, with Masi being replaced by two new people.

The Grand Prix was the final race for 2007 world champion Kimi Räikkönen; the then 42-year-old Finn retired from Formula One after a two-decade career spanning a then-record 349 Grand Prix starts. This was also the final race for Honda as a works power unit supplier until the 2026 Australian Grand Prix in partnership with Aston Martin.
