The Summer Olympic Games, also known as the Games of the Olympiad, and often referred to as the Summer Olympics, is a major international multi-sport event normally held once every four years on leap years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent Games were held in 2021 in Tokyo, Japan. The International Olympic Committee (IOC) is responsible for organising the Games and for overseeing the host city's preparations. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place.The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.

The United States of America has sent many athletes to the celebrations of the Olympic Games, starting with the first modern Olympics held in 1896. Athletes representing the United States have participated in every Olympic Games with the exception of the 1980 Summer Olympics, during which it led a boycott in protest of the Soviet Union's invasion of Afghanistan. The United States Olympic & Paralympic Committee (USOPC) is the National Olympic Committee for the United States.
