ARA Moreno^[A] was a dreadnought battleship designed by the American Fore River Shipbuilding Company for the Argentine Navy. Named after Mariano Moreno, a key member of the first independent government of Argentina, the First Assembly (Primera Junta), Moreno was the second dreadnought of the Rivadavia class, and the fourth built during the South American dreadnought race.

Argentina placed orders for Moreno and its only sister ship, Rivadavia, in reply to a Brazilian naval building program. During their construction, the two dreadnoughts were subject to numerous rumors involving Argentina selling the two battleships to a country engaged in the First World War, but these proved to be false. After Moreno was completed in March 1915, a series of engine problems occurred during the sea trials which delayed its delivery to Argentina to May 1915. The next decade saw the ship based in Puerto Belgrano as part of the Argentine Navy's First Division before sailing to the United States for an extensive refit in 1924 and 1925. During the 1930s the ship was occupied with diplomatic cruises to Brazil, Uruguay, and Europe until the Second World War broke out. During this time, Moreno was employed little as Argentina was neutral. Decommissioned in 1949, Moreno was scrapped in Japan beginning in 1957.
