The French Navy's Invincible was a sister ship to the Gloire, the world's first ocean-going ironclad battleship. It was launched on 4 April 1861. The Gloire class were designed by the French naval architect Dupuy de Lôme. Invincible was the second of the class to be completed.

Invincible's original battery proved to be ineffective against armour, and was replaced in 1868 with breech loaders. Her poor construction, a result of using poor quality timbers, saw her stricken in 1872, after less than 10 years' service.
