This is a list of colonial governors and administrators in the Gambia from the establishment of a British settlement on St Mary's Island, now known as Banjul Island, in 1816, through to the Gambia Colony and Protectorate's independence from the United Kingdom in 1965.

In 1821, the Gambia became a British colony that formed part of Sierra Leone.

Between 1843 and 1866, the Gambia had its own Governor independent of Sierra Leone.

It once again became subordinate in 1866, with an Administrator being appointed to govern the territory.

An independent Governor was again appointed in 1901 that also acted as the Commander-in-Chief of the colony.
