HMS Duff (K352) was a British Captain-class frigate of the Royal Navy that served during World War II. Originally constructed as the United States Navy Buckley class destroyer escort USS Lamons (DE-64), she was transferred to the Royal Navy before she was completed.

The ship was laid down as the U.S. Navy destroyer escort USS Lamons (DE-64) by Bethlehem-Hingham Shipyard, Inc., in Hingham, Massachusetts, on 22 February 1943 and launched on 22 May 1943. Lamons was transferred to the United Kingdom upon completion on 23 August 1943.^[2]

Commissioned into service in the Royal Navy as the frigate HMS Duff (K352) on 23 August 1943 simultaneously with her transfer, the ship served on patrol and escort duty. At 0745 on 30 November 1944, she struck a mine in the North Sea off Ostend, Belgium, suffering three dead. Although badly damaged, she managed to limp back to port at Harwich, England.^[2][3]

Damaged beyond economical repair, Duff was declared a constructive total loss.^[3] The Royal Navy returned her to the U.S. Navy on 28 August 1945.^[2]

The U.S. Navy struck Duff from its Naval Vessel Register on 17 September 1945. She was sold in May 1947 for scrapping in the Netherlands.^[2]
