San Martino was a Regina Maria Pia-class ironclad warship, the second member of her class. She was built for the Italian Regia Marina in the 1860s; like her three sister ships, she was built in France. San Martino was laid down in July 1862, was launched in September 1863, and was completed in November 1864. The ships were broadside ironclads, mounting a battery of four 8-inch (200 mm) and twenty-two 164 mm (6.5 in) guns on the broadside.

San Martino saw action at the Battle of Lissa, fought during the Third Italian War of Independence in 1866. There she was in the center of the action, at the head of the Italian main body. Of the three ships in her division, San Martino was the only vessel to survive the battle. After the war, the ship's career was uneventful, the result of the emergence of more modern ironclads and a severe reduction in the Italian naval budget following their defeat at Lissa. She was rebuilt as a central battery ship some time after Lissa, and was modernized again in the late 1880s. The ship was eventually broken up for scrap in 1903.

San Martino was 81.2 meters (266 ft) long overall; she had a beam of 15.24 m (50.0 ft) and an average draft of 6.35 m (20.8 ft). She had a crew of 480–485 officers and men. She was a broadside ironclad, and she was initially armed with a main battery of four 8 in (203 mm) guns and twenty-two 164 mm (6.5 in) guns, though her armament changed throughout her career. The ship was protected by iron belt armor that was 4.75 in (121 mm) thick and extended for the entire length of the hull at the waterline. The battery deck was protected by 4.3 in (110 mm) of iron plate.
