Dante Alighieri was the first dreadnought battleship built for the Regia Marina (Royal Italian Navy). Completed in 1913, she was the first battleship built with her main armament in triple-gun turrets. The ship served as a flagship during World War I, but saw very little action other than the Second Battle of Durazzo in 1918 where she did not engage enemy forces. She never fired her guns in anger during her career. Dante Alighieri was refitted in 1923, stricken from the Navy List in 1928 and subsequently sold for scrap.

Dante Alighieri was designed by Rear Admiral Engineer Edoardo Masdea, Chief Constructor of the Regia Marina, based on the ideas of General Vittorio Cuniberti who advocated a battleship with main guns of a single caliber and optimized for broadside fire. In addition, the ship's superstructure and funnels were to be kept to a minimum.

The dreadnought was 158.4 meters (519 ft 8 in) long at the waterline, and 168.1 meters (551 ft 6 in) overall. The ship had a beam of 26.6 meters (87 ft 3 in), and a draft of 8.8 meters (28 ft 10 in). She displaced 19,552 tonnes (19,243 long tons) at normal load, and 21,600 tonnes (21,300 long tons) at deep load.Dante Alighieri had two rudders, one behind the other, and a crew of 31 officers and 950 enlisted men.

The ship was propelled by four propeller shafts driven by Parsons steam turbines. Steam for the turbines was provided by 23 Blechynden water-tube boilers, seven of which burned oil and the remaining 16 burned a mixture of oil and coal. The boilers were widely separated in two compartments, each with two funnels, and the turbines were positioned between the two center turrets. Designed to reach a maximum speed of 23 knots (43 km/h; 26 mph) from 35,000 shaft horsepower (26,000 kW),Dante Alighieri failed to reach this goal on her sea trials. The ship only made a maximum speed of 22.83 knots (42.28 km/h; 26.27 mph) using 32,190 shp (24,000 kW). The ship could store a maximum of 3,000 tonnes (3,000 long tons) of coal and an unknown quantity of fuel oil that gave her a range of 4,800 nautical miles (8,900 km; 5,500 mi) at 10 kn (19 km/h; 12 mph), and 1,000 nmi (1,900 km; 1,200 mi) at 22 knots (41 km/h; 25 mph).
