HMS Ferret was an Acheron-class destroyer of the Royal Navy that served during World War I and was sold for breaking in 1921.

She was the sixteenth Royal Navy ship to be named after the domestic mammal Mustela putorius.

[8] Able Seaman George Keeble died of wounds inflicted during the attack,[9] but the ship was not fatally damaged, and she was returned to service.

[13] The provision of converted minelaying destroyers and the availability of reliable H2-pattern mines allowed the greatest allied minelaying operation of World War I - the attempt to close Heligoland Bight to German ships and submarines.

On the night of 27/28 March 1918 while laying a barrier minefield 70 nautical miles (130 km) north-west of Heligoland, Ferret in company with Ariel, Abdiel, Legion and Telemachus[6] came upon three armed German trawlers.
