USS Powhatan (ID–3013) was a transport ship for the United States Navy during World War I. She was originally Hamburg, a Barbarossa-class ocean liner built in 1899 by AG 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.
When the US entered World War I in April 1917, she was seized and converted to a troop transport. Originally commissioned as USS Hamburg (ID-3013), the ship was renamed Powhatan on 5 September 1917. During World War I, she carried 15,274 troops to France and after the war she returned 11,803 servicemen to the United States.
After decommissioning by the US Navy, the ship was turned over to the United States Shipping Board, and chartered for mercantile service until broken up in 1928.
