The men's triple jump event was part of the track and field athletics programme at the 1920 Summer Olympics. The competition was held from Thursday, August 19, 1920, to Saturday, August 21, 1920. Twenty-one triple jumpers from eight nations competed. No nation had more than 4 jumpers, suggesting the limit had been reduced from the 12 maximum in force in 1908 and 1912. The event was won by Vilho Tuulos of Finland, the nation's first medal in the triple jump. Sweden, which had swept the medals in 1912, took the next three places. Erik Almlöf became the third man to win two medals in the event, repeating his bronze performance from 1912.

Sweden competed at the 1920 Summer Olympics in Antwerp, Belgium. 260 competitors, 247 men and 13 women, took part in 100 events in 18 sports.
