HMS Pevensey Castle was a Castle-class corvette built for the United Kingdom's Royal Navy during World War II and saw service during the war as a convoy escort. Following the war, the ship was converted into a weather ship and remained as such until being withdrawn from service in 1981 and scrapped in 1982.

Pevensey Castle, named for the castle in Pevensey, was built by Harland & Wolff in Belfast, and launched on 11 January 1944. The ship was commissioned in June 1944.

In World War II, as part of 30th Escort Group under the command of Denys Rayner, Pevensey Castle shared in the sinking of the German submarine U-1200^[2] south of Ireland on 11 November 1944, along with sister ships Launceston Castle, Portchester Castle and Kenilworth Castle.

In 1960/61 she was converted at Blyth to the weather ship Weather Monitor. She was upgraded at the Manchester Dry Docks Company in 1976 and renamed Admiral Beaufort

She was withdrawn from service in 1981 and scrapped at Troon in 1982.
