List of Olympic Games boycotts

The Olympic Games is a major international multi-sport event.

South Africa were not invited to the 1964 Games, while its invitation to the 1968 Games was withdrawn after several other African countries threatened to boycott the Games due to apartheid. South Africa would not be permitted to return to the Olympics until 1992.

Rhodesia was also prevented from entering the 1972 Summer Olympics when its invitation was withdrawn by the International Olympic Committee following protests by other African countries.

Possibly the most famous Olympic boycotts occurred in 1980 and 1984, due to the Soviet invasion in Afghanistan.

In 2021, several nations announced a diplomatic boycott of the 2022 Winter Olympics to protest against alleged Chinese mistreatment of the Uyghur population, thus prohibiting many government officials from attending the games in an official capacity, while still permitting athletes to compete. Later, India joined the boycott over China's decision to choose Qi Fabao, a regimental commander in the People's Liberation Army, as a torchbearer for the event.
