The tennis tournaments at the 2012 Summer Olympics in London were staged at the All England Club in Wimbledon, from 28 July to 5 August. This was the first Olympic grass court tournament since tennis was reintroduced as an Olympic sport and the first to be held at a Grand Slam venue in the Open era. Two other 2012 Summer Olympic bid finalists had also offered Grand Slam venues. Second-place finisher Paris offered the French Open venue, the Stade Roland Garros, which later was also included in their successful 2024 bid. Meanwhile, fourth-place finisher New York City offered the US Open venue, the USTA Billie Jean King National Tennis Center in Flushing Meadows-Corona Park, Queens.

The All England Lawn Tennis and Croquet Club (AELTC), also known as the All England Club, based at Church Road, Wimbledon, London, England, is a private members' club. It is best known as the venue for the Wimbledon Championships, the only Grand Slam tennis event still held on grass. Initially an amateur event that occupied club members and their friends for a few days each summer, the championships have become far more prominent than the club itself. However, it still operates as a members' tennis club.
