The Enterprise Cup is an annual rugby union competition in Kenya, Tanzania and Uganda, though the competition frequently has the appearance of being an all-Kenyan affair as the majority of rugby clubs in the African Great Lakes region are based in this one country and frequently clubs in Tanzania and Uganda are unable to take part due to financial constraints. The original cup was donated by sailors from HMS Enterprise, who had toured British East Africa in 1928. The only years in which the competition has not been played is between 1940–1946 due to World War II and in 1987 because an international rugby competition was held on RFUEA Ground as part of the All Africa Games.
