The men's triple jump event was part of the track and field athletics programme at the 1920 Summer Olympics.

The event was won by Vilho Tuulos of Finland, the nation's first medal in the triple jump.

Erik Almlöf became the third man to win two medals in the event, repeating his bronze performance from 1912.

Two jumpers from the pre-war 1912 Games returned: bronze medalist Erik Almlöf of Sweden and fourth-place finisher Erling Vinne of Norway.

The competition was described as two rounds at the time, but was more similar to the modern divided final.
