The Olympic Games is a major international multi-sport event. During its history, both the Summer and Winter Games have been the subject of scandals, controversies and incidents.

Cheating, such as the use of performance enhancing drugs by athletes, has regularly affected the Olympic Games. Some countries have boycotted the Games on various occasions, either as a protest against the International Olympic Committee or the contemporary politics of other participants. Some countries have also been banned from the Olympics, such as the defeated countries after both World Wars or South Africa under apartheid. Other controversies have included decisions by referees and gestures by athletes.
