The French Open, also known as Roland-Garros, is a major tennis tournament held over two weeks at the Stade Roland Garros in Paris, France, beginning in late May each year. The tournament and venue are named after the French aviator Roland Garros. The French Open is the premier clay court championship in the world and the only Grand Slam tournament currently held on this surface. It is chronologically the second of the four annual Grand Slam tournaments, occurring after the Australian Open and before Wimbledon and the US Open. Until 1975, the French Open was the only major tournament not played on grass. Between the seven rounds needed for a championship, the clay surface characteristics, and the best-of-five-set men's singles matches, the French Open is widely regarded as the toughest and most physically demanding tournament in tennis.

A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the centre. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.
