The men's 100 metre butterfly event at the 1972 Olympic Games took place between August 30 and 31. This swimming event used the butterfly stroke. Because an Olympic size swimming pool is 50 metres long, this race consisted of two lengths of the pool.

The winning margin was 1.29 seconds which as of 2023 remains the only time this event for men was won by more than one second at the Olympics.
