HMS Caicos was a Colony-class frigate of the United Kingdom that served during World War II. She was originally ordered by the United States Navy as the Tacoma-class patrol frigate USS Hannam and was transferred to the Royal Navy prior to completion. It was named after the Caicos Islands.

The Colony-class frigates were a series of 21 frigates constructed in the United States by the Walsh-Kaiser Company of Providence, Rhode Island, for transfer under Lend-Lease to the Royal Navy in 1944. Each was named after a relatively minor Crown colony or other constituent territory of the British Commonwealth and Empire. Names of large British colonies had been used for the Crown Colony-class cruisers.
