HMS Ithuriel was a Marksman-class flotilla leader of the British Royal Navy. Originally to have been named Gabriel, the name was changed before her launch. The ship was built by Cammell Laird at Birkenhead, being launched on 8 March 1916 and entering service in August that year. Ithuriel served with the Grand Fleet during the First World War, leading both a destroyer flotilla and a submarine flotilla. She survived the war, before being sold for scrap on 8 November 1921.
