2015 French Open – Men's Singles

Rafael Nadal was the five-time defending champion, but Novak Djokovic defeated him in the quarterfinals. This was just Nadal's second career defeat here and ended his record win streak of 39 matches. Nadal had won all six of their prior matches here, each during one of his record nine title runs. Also, Stan Wawrinka defeated 2009 champion Roger Federer in the quarterfinals, meaning that for the first time since 2004, neither Nadal nor Federer reached the final and won the title.

Wawrinka defeated Djokovic in the final, 4–6, 6–4, 6–3, 6–4, to win his first French Open and second Grand Slam title. During both of his title runs he defeated the top two seeds.
