2017 French Open – Men's singles

Rafael Nadal defeated Stan Wawrinka in the final, 6–2, 6–3, 6–1 to win the men's singles tennis title at the 2017 French Open. It was his record-extending tenth French Open title and 15th major title overall. Nadal became the first man to win ten singles titles at the same major. He did not lose a set during the tournament for a third time (after 2008 and 2010), not losing more than four games in any set played. He lost only 35 games during the tournament, his personal best, and the second-best in the tournament's history after Björn Borg in 1978. Nadal also became the third man, after Ken Rosewall and Pete Sampras, to win a major title in his teens, twenties, and thirties.

Novak Djokovic was the defending champion, but lost to Dominic Thiem in the quarterfinals. Djokovic was attempting to become the first man in the Open Era to achieve a double career Grand Slam. This was the first time since 2010 that he did not reach at least the semifinals at the French Open.

The hard-fought semifinal between Wawrinka and Andy Murray marked the end for both players at the very top of the sport, as both suffered injuries that took them out of the game for months, from which they did not reclaim their prior preeminence.

This marked the first major appearance of future ATP Finals champion and two-time major finalist Stefanos Tsitsipas, who lost to Ivo Karlović in the first round.
