The Italian cruiser Pisa was the name ship of her class of two armored cruisers built for the Royal Italian Navy (Regia Marina) in the first decade of the 20th century. The ship participated in the Italo-Turkish War of 1911–12, during which she supported the occupations of Tobruk, Libya and several islands in the Dodecanese and bombarded the fortifications defending the entrance to the Dardanelles. During World War I, Pisa's activities were limited by the threat of Austro-Hungarian submarines, although the ship did participate in the bombardment of Durazzo, Albania in late 1918. After the war she became a training ship and was stricken from the Navy List in 1937 before being scrapped.

Pisa had a length between perpendiculars of 130 meters (426 ft 6 in) and an overall length of 140.5 meters (460 ft 11 in). She had a beam of 21 meters (68 ft 11 in) and a draft of 7.1 meters (23 ft 4 in). The ship displaced 9,832 metric tons (9,677 long tons) at normal load, and 10,600 metric tons (10,400 long tons) at deep load. The Pisa-class ships had a complement of 32 officers and 652 to 655 enlisted men.

The ship was powered by two vertical triple-expansion steam engines, each driving one propeller shaft using steam supplied by 22 Belleville boilers. Designed for a maximum output of 20,000 indicated horsepower (15,000 kW) and a speed of 22.5 knots (41.7 km/h; 25.9 mph),Pisa handily exceeded this, reaching a speed of 23.47 knots (43.47 km/h; 27.01 mph) during her sea trials from 20,808 ihp (15,517 kW). She had a cruising range of about 2,500 nautical miles (4,600 km; 2,900 mi) at a speed of 12 knots (22 km/h; 14 mph).
