HMS Diamond was a D-class destroyer built for the Royal Navy in the early 1930s. The ship spent the bulk of her career on the China Station. She was briefly assigned to the Mediterranean Fleet in 1939 before she was transferred to West Africa for convoy escort duties. Diamond returned to the Mediterranean Fleet in early 1940 where she generally escorted convoys to and from Malta. The ship participated in the Battle of Cape Spartivento in November. Diamond was sunk by German aircraft on 27 April 1941 whilst evacuating Allied troops from Greece.
