SS Cantabria was a Spanish-owned cargo steamship that was built in 1919 in Canada and sunk in 1938 in a naval action in the Spanish Civil War in the North Sea. She was built as War Chief, renamed Alfonso Pérez shortly after she was built, and renamed Cantabria during the Spanish Civil War. Cantabria's wreck is off the coast of Norfolk, 12 miles ENE of Cromer. She was shelled by the Spanish Nationalist auxiliary cruiser Nadir.
