SMS Leopard was a British cargo steamship that was built in 1912 as Yarrowdale, captured in 1916 by the Imperial German Navy, converted into a commerce raider in Germany, and sunk with all hands by the Royal Navy in 1917. Yarrowdale's British operator was Robert Mackill & Co of Glasgow, who gave this name to at least three different ships. This was the second of the three. Leopard was the last commerce raider that Germany sent out in the First World War. After the Royal Navy sank her, Germany relied entirely on U-boats to sink Allied merchant ships.
