Antinous was a Design 1015 ship steam cargo ship built in 1919–1920 by Guy M. Standifer Construction Company of Vancouver for the United States Shipping Board as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The vessel was chiefly employed on the Gulf to Europe routes throughout her career. In September 1942, while on a passage to British Guiana to load her cargo, she was torpedoed and sunk by German submarines operating at the time in the Caribbean.
