HMS Shearwater was a Kingfisher-class sloop of the Royal Navy.

She served during the Second World War and was adopted by Farnborough Urban District Council during Warship Week in 1942.

Her anti-aircraft armament was augmented during the war, with the addition of two single 20mm Oerlikon cannon atop the aft shelter.

She was the fictional HMS Winger in Nicholas Monsarrat's book 'Corvette Command' of the Three Corvettes series.

This vessel was also the very first sloop to be commanded by an RNVR officer from June 1944 until July 1945, Desmond Henry Cope, DSC(1943).
