HMS Curacoa was a C-class light cruiser built for the Royal Navy during the First World War. She was one of the five ships of the Ceres sub-class and spent much of her career as a flagship.

 

The ship was assigned to the Harwich Force during the war, but saw little action as she was completed less than a year before the war ended. Briefly assigned to the Atlantic Fleet in early 1919, Curacoa was deployed to the Baltic in May to support anti-Bolshevik forces during the British campaign in the Baltic during the Russian Civil War. Shortly thereafter the ship struck a naval mine and had to return home for repairs.

After spending the rest of 1919 and 1920 in reserve, she rejoined the Atlantic Fleet until 1928, aside from a temporary transfer to the Mediterranean Fleet in 1922–1923 to support British interests in Turkey during the Chanak Crisis. Curacoa was transferred to the Mediterranean Fleet in 1929.

In 1933, Curacoa became a training ship and in July 1939, two months before the start of the Second World War, she was converted into an anti-aircraft cruiser. She returned to service in January 1940 and, while providing escort in the Norwegian Campaign that April, was damaged by German aircraft. After repairs were completed that year, she escorted convoys in and around the British Isles for two years. In late 1942, during escort duty, she was accidentally sliced in half and sunk by the ocean liner RMS Queen Mary, with the loss of 337 men.
