USS Powhatan (ID–3013) was a transport ship for the United States Navy during World War I. She was originally the SS Hamburg, a Barbarossa-class ocean liner built in 1899 by Aktiengesellschaft Vulkan of Stettin, Germany, for the Hamburg America Line. At the outset of World War I the ship was interned by the United States. She was soon chartered by the American Red Cross to take medical personnel and supplies to Europe. Renamed Red Cross, she left New York in mid-September, 1914.
