Tennis at the 2012 Summer Olympics
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.
