SS Alcantara was an ocean liner that went into service just weeks before the start of World War I, was converted to an armed merchant cruiser in 1915, and was sunk by the German cruiser Greif on 29 February 1916.

Alcantara was built by Harland & Wolff for Royal Mail Lines, launched in October 1913 and made her maiden voyage in June of 1914, following a Southampton-South America route.

In 1915 the ship was outfitted with eight 6-inch guns, anti-aircraft guns and depth charges, and commissioned as HMS Alcantara.
