The men's 1500 metres event was part of the track and field athletics programme at the 1920 Summer Olympics. The competition was held on Wednesday, August 18, 1920, and on Thursday, August 19, 1920. Twenty-nine runners from 12 nations competed. No nation had more than 4 runners, suggesting the limit had been reduced from the 12 maximum in force in 1908 and 1912. The event was won by Albert Hill of Great Britain, completing his middle-distance double (gold in the 800 metres and 1500 metres). It was the nation's second consecutive and third overall championship in the men's 1500 metres.
