The Gambia Regiment was a British Colonial Auxiliary Forces regiment raised in the Gambia Colony and Protectorate that existed between 1901 and 1958. Known as the Gambia Company from 1901 to 1939 and from 1945 to 1950, its strength fluctuated from peacetime and wartime, peaking at two battalions during World War II. The unit saw active service in both world wars, participating in the Kamerun and East African campaigns during World War I and in the Burma campaign during World War II. It was organisationally part of the larger Royal West African Frontier Force, and was part of the 81st Division in World War II.

The West African Frontier Force (WAFF) was a multi-battalion field force, formed by the British Colonial Office in 1900 to garrison the West African colonies of Nigeria, Gold Coast, Sierra Leone and Gambia. In 1928, it received royal recognition, becoming the Royal West African Frontier Force (RWAFF).
