The 2015 French Open was a tennis tournament played on outdoor clay courts. It was the 119th edition of the French Open and the second Grand Slam event of the year. It took place at the Stade Roland Garros from 24 May to 7 June and consisted of events for professional players in singles, doubles and mixed doubles play. Junior and wheelchair players also took part in singles and doubles events.

A clay court is one of the types of tennis court on which the sport of tennis is played. Clay courts are built on a foundation of crushed stone, brick, shale, and other aggregate, with a thin layer of fine clay particles on top. Clay courts are more common in Continental Europe and Latin America than in North America, Asia-Pacific or Britain. The only Grand Slam tournament that uses clay courts is the French Open.
