Marceau was an ironclad built for the French Navy during the 1880s, the lead ship of her class. She served in the Mediterranean Squadron until 1900, when she was rebuilt and subsequently placed in reserve. She returned to service in 1906 as a torpedo training ship. During World War I, she served in Malta and Corfu as a submarine tender. The old ironclad was sold for scrapping in 1920, and while being towed to Toulon, she ran aground in a gale off Bizerte and became stranded. The wreck remained visible there until the 1930s.
