HMS Gambia was a Fiji-class light cruiser of the Royal Navy. She was in the service of the Royal New Zealand Navy (RNZN) as HMNZS Gambia from 1943 to 1946. She was named after the then Crown colony of the Gambia, and has been the only ship of the Royal Navy to bear the name.

The Fiji-class cruisers were a class of eleven light cruisers of the Royal Navy that saw extensive service throughout the Second World War. Each ship of the class was named after a Crown colony or other constituent territory of the British Commonwealth and Empire. The class was also known as the Colony class, or Crown Colony class. Developed as more compact versions of the preceding Town-class cruisers, the last three were built to a slightly modified design and were sometimes also called the Ceylon class.
