1968 French Open – Men's singles

Ken Rosewall defeated Rod Laver in the final, 6–3, 6–1, 2–6, 6–2 to win the men's singles tennis title at the 1968 French Open. It was Rosewall's second French title and fifth Grand Slam tournament title overall. The tournament was the first major of the Open Era, in which professionals were allowed to compete against amateurs. Rosewall and Laver, who had not appeared in a Grand Slam tournament since 1956 and 1962 respectively, were among those no longer barred from entering.

Roy Emerson was the defending champion, but lost in the quarterfinals to Pancho Gonzales.

Missing from the tournament were WCT's "Handsome Eight" and top amateurs Manuel Santana, Arthur Ashe, Clark Graebner and Tom Okker.

It was future champion and future world No. 1 Ilie Năstase's first major appearance.
