At the 1908 Summer Olympics, a water polo tournament was contested.

The 1908 Summer Olympics were an international multi-sport event held in London, England, United Kingdom, from 27 April to 31 October 1908. The 1908 Games were originally scheduled to be held in Rome, but were relocated on financial grounds following the violent eruption of Mount Vesuvius in 1906, which claimed over 100 lives; Rome eventually hosted the Games in 1960.
