The fourth HMS Torrington (K577) was a British Captain-class frigate of the Royal Navy in commission during World War II.

The ship was laid down as the unnamed U.S. Navy destroyer escort DE-568 by Bethlehem-Hingham Shipyard, Inc., in Hingham, Massachusetts, on 22 September 1943 and launched on 27 November 1943.

The ship was commissioned into service in the Royal Navy [2] as the frigate HMS Torrington (K577) on 18 January 1944 simultaneously with her transfer.

After shakedown in Casco Bay, Maine, and off Bermuda, she steamed to St. John's and Naval Station Argentia in the Dominion of Newfoundland before proceeding to England.

On 21 July 1944, Torrington saw her first combat, joining the escort destroyer HMS Melbreak (L73) in action against a German destroyer and four German S-boat – known to the Allies as "E-boat" – motor torpedo boats off Cap d'Antifer, France, preventing them from interfering with the flow of Allied supplies supporting the invasion of Normandy.
