The 2021 Abu Dhabi Grand Prix was the final race of the 2021 Formula One World Championship, held on December 12, 2021, at the Yas Marina Circuit in Abu Dhabi, United Arab Emirates. The race decided both the Drivers and Constructors championships, with Max Verstappen and Lewis Hamilton both having 369.5 points coming into the race. Verstappen won the race, securing his maiden drivers championship. The race was controversial, with Hamilton leading for much of the race but Verstappen passing him on the final lap to win the championship. The controversy continued after the race, with Mercedes initially planning to appeal the result but later withdrawing their intention to appeal. The FIA conducted their own investigation and ultimately decided to sack Michael Masi, the race director, ahead of the 2022 F1 season. The race is considered one of the most dramatic title deciders in Formula One history.
