The men's shot put event was part of the track and field athletics programme at the 1920 Summer Olympics. The competition was held on Tuesday, August 17, 1920, and on Wednesday, August 18, 1920. Twenty shot putters from ten nations competed. No nation had more than 4 athletes, suggesting the limit had been reduced from the 12 maximum in force in 1908 and 1912. The event was won by Ville Pörhölä of Finland, the first time the men's shot put was won by someone not from the United States. Fellow Finn Elmer Niklander took silver. The Americans, who had won all five previous editions of the shot put, including three medal sweeps, settled for bronze by Harry B. Liversedge.

Elmer Konstantin Niklander was a Finnish athlete who competed in throwing events, winning the gold medal in the 1920 discus throw and three other Olympic medals and 44 Finnish championships.
