The 1926 French Championships (now known as the French Open) was a tennis tournament that took place on outdoor clay courts at the Croix-Catelan of the Racing Club de France in Paris, France. The tournament ran from 2 June until 14 June. It was the 31st staging of the French Championships and the second Grand Slam tournament of the year. Suzanne Lenglen repeated her feat of winning every event she was eligible for, in her final year of competition before she turned professional; the tournament was also notable for being the first time American competitors won a title, Vincent Richards and Howard Kinsey in the men's doubles.
