The Championships, Wimbledon, commonly known simply as Wimbledon or The Championships, is the oldest tennis tournament in the world, and is regarded by many as the most prestigious. It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, and since 2009 with a retractable roof over Centre Court.

Wimbledon is one of the four Grand Slam tennis tournaments, the others being the Australian Open, the French Open and the US Open. Since the Australian Open shifted to hard court in 1988, Wimbledon is the only major still played on grass, which is widely considered as the classic tennis court.

The tournament traditionally took place over two weeks in late June and early July, starting on the last Monday in June and culminating with the Ladies’ and Gentlemen’s Singles Finals, scheduled for the Saturday and Sunday at the end of the second week. However, recent changes to the tennis calendar have seen the event moved back by a week to begin in early July. Five major events are held each year, with additional junior and invitational competitions also taking place.
