HMS Cochrane was a Warrior-class armoured cruiser built for the Royal Navy in the first decade of the 20th century. She served in the 2nd Cruiser Squadron during the First World War under Rear-Admiral Herbert Heath, taking part in the Battle of Jutland in 1916. She was based in Murmansk in mid-1918 during the Allied intervention in the Russian Civil War. She became stranded in the River Mersey on 14 November 1918 and broke in two. The wreck was broken up in place by June 1919.
