Henri IV was a pre-dreadnought battleship of the French Navy built to test some of the ideas of the prominent naval architect Louis-Émile Bertin. She began World War I as guardship at Bizerte. She was sent to reinforce the Allied naval force in the Dardanelles campaign of 1915, although some of her secondary armament had been removed for transfer to Serbia in 1914. Afterwards, she was relegated to second-line roles before being sent to Taranto as a depot ship in 1918. She was struck from the navy list in 1920 and scrapped the following year.
