The French ironclad Invincible was the second of the three wooden-hulled Gloire-class ironclads built for the French Navy in 1858–62. The ships of the Gloire class were classified as armoured frigates because they only had a single gun deck and their traditional disposition of guns arrayed along the length of the hull also meant that they were broadside ironclads. Invincible had an uneventful career and was deployed in North American waters during the Franco-Prussian War of 1870–71. The unseasoned timber of her hull rotted quickly and she was condemned in 1872 and scrapped in 1876.
