HMS Carnarvon was a Devonshire-class armoured cruiser (10,850 tons displacement) of the Royal Navy. She has been the only ship of the navy to be named after the town of Caernarfon in Wales. Launched in 1903, she served with the Mediterranean Fleet in the 3rd Cruiser Squadron until March 1907, and then joined the 2nd Cruiser Squadron in the Atlantic Fleet. She then moved to the 3rd Division of the Home Fleet in April 1909 and in March 1912 she transferred again to the 2nd Fleet at Devonport and became the flagship of the 5th Cruiser Squadron until the outbreak of World War I.
Carnarvon captured the German merchant ship SS Professor Woermann on 23 August 1914 after moving to Cape Verde at the beginning of that month. She moved to Montevideo in October 1914 and later led cruisers at the Battle of the Falkland Islands on 8 December 1914. In March 1915, after repairs were completed at Rio de Janeiro for tears to her plating, she continued to serve on the North American and West Indies Station until November 1918. In 1919 she served as a cadets' training ship until sold in March 1921 and broken up on 8 November 1921.
