Antonio López was a merchant steamship that was built in Scotland in 1882 for the Spanish Compañía Transatlántica Española (CTE). A United States Navy auxiliary cruiser sank her in the Spanish–American War when she was trying to run the US blockade to supply materiél to the Spanish garrison on Puerto Rico. She is now the only known Spanish shipwreck in US waters from the war. Her wreck site, in 1,700 feet (520 m) of water off Dorado, Puerto Rico, was designated a National Historic Landmark in 1997.

Compañía Transatlántica Española, S.A., also known as the Spanish Line in English, was a passenger ocean line that has largely ceased operations although it still exists as a company. It is popularly known as "La Trasatlántica" in the Spanish language.
