The French Open (French: Les Internationaux de France de Roland Garros or Tournoi de Roland-Garros) is a major tennis tournament held over two weeks between late May and early June in Paris, France, at the Stade Roland Garros. It is the second of the Grand Slam tournaments on the annual tennis calendar and the premier clay court tennis tournament in the world. Roland Garros is the only Grand Slam still held on clay and ends the spring clay court season.

It is one of the most prestigious events in tennis, and it has the widest worldwide broadcasting and audience of all regular events in this sport. Because of the slow playing surface and the five-set men's singles matches without a tiebreak in the final set, the event is widely considered to be the most physically demanding tennis tournament in the world.

The singles champions for 2009 are the Swiss Male Roger Federer and the Russian Female Svetlana Kuznetsova.
