The Infanta Maria Teresa class of three armored cruisers were built for the Spanish Navy between 1889 and 1893. All three were sunk in action against the United States Navy during the Battle of Santiago de Cuba in 1898.

Pelayo was a battleship of the Spanish Navy which served in the Spanish fleet from 1888 to 1925. She was the first battleship and the most powerful unit of the Spanish Navy at the time. Despite its modern design for the time, Pelayo and the rest of the Spanish Asia-Pacific Rescue Squadron never engaged in combat during the Spanish–American War. Some historians have argued that had the battleship, along with the modern armored cruiser Carlos V, participated directly in the conflict the course of the war would have been altered dramatically and possibly lead to a Spanish victory, thus retaining Spain's status as a colonial power.
