Fencing at the 1972 Summer Olympics – Men's sabre

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.

The three world champions since the last Olympics were Viktor Sidyak of the Soviet Union (1969), Pézsa (1970), and Michele Maffei of Italy (1971).

The 1972 format also eliminated the 8-fencer final pools of previous Games; for all rounds after the first, the number of fencers was set at 6.

The final resulted in a clear victory for Sidyak, but a three-way tie for second place.
