HMS Cressy was a Cressy-class armoured cruiser built for the Royal Navy around 1900. Upon completion she was assigned to the China Station. In 1907 she was transferred to the North America and West Indies Station before being placed in reserve in 1909. Recommissioned at the start of World War I, she played a minor role in the Battle of Heligoland Bight a few weeks after the beginning of the war. Cressy, together with two of her sister ships, was torpedoed and sunk by the German submarine U-9 on 22 September 1914 with the loss of 560 of her crew.
