The men's sabre was one of eight fencing events on the fencing at the 1972 Summer Olympics programme. It was the seventeenth appearance of the event. The competition was held from 30 to 31 August 1972. 53 fencers from 22 nations competed. Nations had been limited to three fencers each since 1928. The event was won by Viktor Sidyak of the Soviet Union, the nation's first victory in the event (tying the nation with Cuba, France, Greece, Italy, and Poland for second-most all-time, behind Hungary's 11). Hungary had lost its nine-Games gold medal streak in 1968 but remained a power in the event; Péter Marót took silver to extend Hungary's podium streak to 11 Games. Another Soviet, Vladimir Nazlymov, earned bronze.
