SS Express was a Type C3-E cargo ship of American Export Lines that was sunk by Japanese submarine I-10 in June 1942 in the Indian Ocean. The ship, built in 1940 by Bethlehem Shipbuilding in Quincy, Massachusetts, was one of eight sister ships built for the United States Maritime Commission on behalf of American Export Lines. Out of a total of 55 men aboard the ship at the time of her torpedoing, 13 were killed; most of the other 42 landed on the coast of Mozambique six days after the sinking.
