2026 French Open – Men's singles

Alexander Zverev defeated Flavio Cobolli in the final, 6–1, 4–6, 6–4, 6–7, 6–1, to win the men's singles tennis title at the 2026 French Open. It was his first major title, following three previous runner-up outcomes. Zverev was the first German man to win the French Open since Henner Henkel in 1937 and the first to win any singles major since Boris Becker at the 1996 Australian Open. By reaching the final, Cobolli made his top 10 debut in the ATP rankings. This was the third consecutive year that the men's singles final went to five sets.

Carlos Alcaraz was the two-time reigning champion, but withdrew before the tournament due to a wrist injury. This marked Alcaraz's first absence from a major since the 2023 Australian Open.

Jannik Sinner's loss to Juan Manuel Cerúndolo in the second round ended a streak of nine consecutive major titles won between him and Alcaraz, dating to the 2024 Australian Open, as well as his career-best winning streak of 30 matches. This marked the first time since 2000 that the reigning world No. 1 failed to reach the third round of the French Open. At 5 hours and 58 minutes, the third-round match between Cerúndolo and Martín Landaluce was the longest match at any major with a final-set tiebreak. It was the third-longest match in the tournament's history.

By making his 82nd major appearance, Novak Djokovicset the record for the most total major main draw appearances. Djokovic's defeat to João Fonseca in the third round marked only the second time (after the 2010 French Open) that he lost at a major after leading two sets to love, and the first time since 2009 that he failed to reach the quarterfinals at the French Open. Djokovic's defeat guaranteed a first-time Grand Slam men's singles champion. This marked the first time in the Open Era that no former major champions had reached the round-of-16 stage of a major, and the first major to have no former champions reach the semifinals of both the men's and women's singles events since the 1977 French Open.

This was the first time since the 2022 Wimbledon Championships, and the third time overall in the Open Era (after the 1992 Australian Open) that a semifinal match at a major resulted in a walkover.

Félix Auger-Aliassime became the first Canadian player to reach the quarterfinals of all four majors. For the first time in the Open Era, three Italian men (Cobolli, Matteo Arnaldi and Matteo Berrettini) reached the quarterfinals of a single major. Ranked No. 105, Berrettini was the lowest-ranked quarterfinalist at the French Open since Igor Andreev in 2007. Fonseca was the first Brazilian man to reach the quarterfinals at the French Open since Gustavo Kuerten in 2004. Jesper de Jong was the third lucky loser in the Open Era to reach the fourth round of the French Open, and the first since David Goffin in 2012. Also entering as a lucky loser, Coleman Wong became the first player from Hong Kong to participate in the main draw of the French Open in the Open Era. Moïse Kouamé was the youngest male player to reach the third round of a major since Rafael Nadal at the 2003 Wimbledon Championships.

This tournament marked the final French Open appearances of 2015 champion, three-time major champion and former world No. 3 Stan Wawrinka, and former world No. 6 Gaël Monfils. Both players lost in the first round, to de Jong and Hugo Gaston, respectively.
