The Regina Elena class was a group of four pre-dreadnought battleships built for the Italian Regia Marina between 1901 and 1908. The class comprised four ships: Regina Elena, the lead ship, Vittorio Emanuele, Roma, and Napoli. Designed by Vittorio Cuniberti, they were armed with a main battery of two 12-inch (305 mm) guns and twelve 8 in (203 mm) guns, and were capable of a top speed of 22 knots (41 km/h; 25 mph). They were the fastest battleships in the world at the time of their commissioning, faster even than the British turbine-powered HMS Dreadnought.
The ships saw service during the Italo-Turkish War of 1911–1912 with the Ottoman Empire. They frequently supported Italian ground forces during the campaigns in North Africa and the islands of the eastern Mediterranean Sea. They served during World War I, in which Italy participated from 1915 to 1918, but they saw no combat as a result of the cautious policies adopted by the Italian and Austro-Hungarian navies. All four ships were discarded between 1923 and 1926 and broken up for scrap.
