At the 1900 Summer Olympics, a polo tournament was contested. Matches were held on 28 May, 31 May, and 2 June. Five teams competed. Most of the teams were of mixed nationality, with British athletes competing on three teams. There was no playoff for third place.
Three out of the four medals were won by mixed teams. The United States and Great Britain had competitors on both the gold and the silver medal teams. Great Britain and France both had players on one of the bronze medal teams, while Mexico took the other bronze by itself.
