The Regina Maria Pia class was a group of four ironclad warships built for the Italian Regia Marina in the 1860s. The class comprised four ships, Regina Maria Pia, San Martino, Castelfidardo, and Ancona. They were built by French shipyards, since Italian yards were unable to meet the demand of the rapidly expanding Italian fleet. The ships were broadside ironclads and mounted a battery of twenty-six muzzle loading guns.

The Roma class was a pair of ironclad warships built for the Italian Regia Marina in the 1860s and 1870s. The class comprised two ships, Roma and Venezia. Roma was a broadside ironclad armed with five 254 mm (10 in) and twelve 203 mm (8 in) guns, while Venezia was converted into a central battery ship during construction, armed with a much more powerful battery of eighteen 10-inch guns. Neither ship had an eventful career, due in large part to their rapid shift to obsolescence. Venezia and Roma were withdrawn from service for auxiliary duties in 1880 and 1890, respectively. Both were stricken from the naval register in 1895 and broken up for scrap the following year, Roma having been badly damaged in a fire in 1895.
