HMS Grafton (H89) was a G-class destroyer built for the Royal Navy during the mid-1930s. During the Spanish Civil War of 1936–1939 the ship spent considerable time in Spanish waters, enforcing the non-intervention measures agreed by Britain and France. After the beginning of World War II she was transferred from the Mediterranean Fleet to Great Britain for escort and contraband inspection duties. Grafton was refitting when the Norwegian Campaign began in April 1940, but the ship escorted convoys to Norway once her refit was completed. She evacuated British troops from the Dunkirk bridgehead in May, but was sunk by a German submarine after she stopped to rescue survivors from another British destroyer.

While rescuing survivors from Wakeful off Nieuwpoort, Belgium, Grafton was struck in the stern by a torpedo from the German submarine . This seriously damaged the ship, and also triggered a secondary explosion which damaged the bridge, killing the captain and another officer. Thirteen ratings and the canteen manager were also killed. The ship's back was broken, but she remained afloat long enough for all survivors to be rescued by the destroyer and the transport Malines. Ivanhoe sank Grafton with naval gunfire, as she was too badly damaged to be towed to safety.
