HMS Wigtown Bay (K616) was a Bay-class anti-aircraft frigate of the British Royal Navy. She was named for Wigtown Bay in Galloway. Ordered on 6 March 1943 from the Harland and Wolff yard in Belfast as a Loch-class anti-submarine frigate, and assigned the name Loch Garasdale, the ship was laid down on 24 October 1944 (yard number 1260). However, during construction the need for anti-aircraft escorts for service in the Far East, meant that the contract was revised, and she was completed as a Bay class frigate. The ship was named Wigtown Bay when launched on 26 April 1945.
