HMS Cooke (K471) was a British Captain-class frigate of the Royal Navy in commission during World War II. Originally constructed as the United States Navy Evarts-class destroyer escort USS Dempsey (DE-267), she served in the Royal Navy from 1943 to 1946.

The ship was laid down as the U.S. Navy destroyer escort USS Dempsey (DE-267), the first ship of the name, by the Boston Navy Yard in Boston, Massachusetts, on 11 March 1943^[2] and launched on 22 April 1943, sponsored by Mrs. J. A. Dempsey, mother of the late Lieutenant, junior grade Richard John Dempsey (1919-1942), for whom the ship was named. Dempsey was transferred to the United Kingdom under Lend-Lease upon completion on 23 August 1943.

Commissioned into service in the Royal Navy as HMS Cooke (K471) on 23 August 1943^[1] simultaneously with her transfer, the ship served on patrol and escort duty. On 29 June 1944 she joined the British frigates Domett, Duckworth, and Essington and a Royal Air Force Liberator aircraft of No. 244 Squadron in a depth charge attack that sank the German submarine U-988 in the English Channel west of Guernsey at 49°37′00″N 003°41′00″W / 49.61667°N 3.68333°W / 49.61667; -3.68333 (U-988 sunk). On 26 July 1944, she sank the German submarine U-214 with depth charges in the English Channel southeast of the Eddystone Rocks in position 49°58′00″N 003°30′00″W / 49.96667°N 3.50000°W / 49.96667; -3.50000 (U-214 sunk).^[1]

The Royal Navy returned Cooke to the U.S. Navy on 5 March 1946.

The United States sold Cooke on 3^[1][3] or 10^[2][4] June 1947 (sources vary) for scrapping.
