Ernest Renan was an armored cruiser built for the French Navy in the first decade of the 20th century. At the outbreak of World War I in August 1914, she participated in the hunt for the German battlecruiser and then joined the blockade of the Austro-Hungarian Navy in the Adriatic. She took part in the Battle of Antivari later in August, and the seizure of Corfu in January 1916, but saw no further action during the war. After the war, the British and French intervened in the Russian Civil War; this included a major naval deployment to the Black Sea, which included "Ernest Renan". She served as a training ship in the late 1920s before she was sunk as a target ship in the 1930s.
