The French Open, often referred to as Roland Garros, is a major tennis tournament held over two weeks between late May and early June at the Stade Roland Garros in Paris, France. Named after the French aviator Roland Garros, it is the premier clay court tennis championship event in the world and the second of four annual Grand Slam tournaments, the other three being the Australian Open, Wimbledon and the US Open. Roland Garros is the only Grand Slam event held on clay and ends the clay court season.
