Cape Helles is the rocky headland at the southwesternmost tip of the Gallipoli peninsula, Turkey. It was the scene of heavy fighting between Ottoman Turkish and British troops during the landing at Cape Helles at the beginning of the Gallipoli campaign in 1915. The name derives from the mythical Greek princess Helle who drowned in the Hellespont; 'Helles' is genitive of 'Helle' in the ancient Greek language.
