Solférino was a broadside ironclad warship of the French Navy, the second unit of the Magenta class, designed by Henri Dupuy de Lôme and launched in 1861. She was named in honour of the Battle of Solferino.

These two ironclads were the only two-decked broadside ironclad battleships ever built. They were also the first ships in the world to be equipped with a spur ram. They were somewhat of an enlarged version of the Gloire type armoured frigate, or the result of the same principle applied to a full-scale ship of the line.
