Andrea Doria was the lead ship of her class of battleships built by the Regia Marina. The class included only one sister ship, Duilio. Andrea Doria was named after the 16th-century Genoese admiral of the same name. Laid down in March 1912, the battleship was launched a year later in March 1913, and completed in March 1916. She was armed with a main battery of thirteen 305 mm (12.0 in) guns and had a top speed of 21 knots.

The Andrea Doria class was a pair of dreadnought battleships built for the Royal Italian Navy between 1912 and 1916. The two ships—Andrea Doria and Duilio—were completed during World War I. The class was an incremental improvement over the preceding Conte di Cavour class. Like the earlier ships, Andrea Doria and Duilio were armed with a main battery of thirteen 305-millimeter (12.0 in) guns.
