The men's 1500 metres was a middle-distance running event on the athletics programme at the 1900 Summer Olympics in Paris. It was held on July 15, 1900. The race was held on a track of 500 metres in circumference. Nine athletes from six nations competed. The event was won by Charles Bennett of Great Britain, the nation's first medal in the brief history of the event.

The 1500 metres or 1,500-metre run is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983. It is equivalent to 1.5 kilometers or approximately 15⁄16 miles. The event is closely associated with its slightly longer cousin, the mile race, from which it derives its nickname "the metric mile".
