The 1972 Summer Olympics (German: Olympische Sommerspiele 1972), officially known as the Games of the XX Olympiad, was an international multi-sport event held in Munich, West Germany, from August 26 to September 11, 1972.

The sporting nature of the event was largely overshadowed by the Munich massacre in which eleven Israeli athletes and coaches and a West German police officer were killed by Black September Palestinian terrorists.

The 1972 Summer Olympics were the second Summer Olympics to be held in Germany, after the 1936 Games in Berlin, which had taken place under the Nazi regime. Mindful of the connection, the West German Government was eager to take the opportunity of the Munich Olympics to present a new, democratic and optimistic Germany to the world, as shown by the Games' official motto, "Die Heiteren Spiele", or "the cheerful Games". The logo of the Games was a blue solar logo (the "Bright Sun") by Otl Aicher, the designer and director of the visual conception commission. The Olympic mascot, the dachshund "Waldi", was the first officially named Olympic mascot. The Olympic Fanfare was composed by Herbert Rehbein, a companion of Bert Kaempfert.

The Olympic Park (Olympiapark) is based on Frei Otto's plans and after the Games became a Munich landmark. The competition sites, designed by architect Günther Behnisch, included the Olympic swimming hall, the Olympics Hall (Olympiahalle, a multipurpose facility) and the Olympic Stadium (Olympiastadion), and an Olympic village very close to the park. The design of the stadium was considered revolutionary, with sweeping canopies of acrylic glass stabilized by metal ropes, used on such a large scale for the first time.
