SS Mission Soledad was a Type T2-SE-A2 tanker built for the United States Maritime Commission during World War II.

Mission Soledad was laid down 12 July 1943 under a Maritime Commission contract by Marine Ship Corporation, Sausalito, California; launched 28 September 1943; sponsored by Mrs. Atholl McBean; delivered 16 January 1944.

When operational control of this tanker was assumed by the newly created Military Sea Transportation Service on 1 October 1949, she was redesignated USNS Mission Soledad (T-AO-136).

Mission Soledad rushed to the scene and rendered assistance until USS Pecos (AO-65) arrived and began towing the stricken ship into Bombay, India.

Upon completion of the conversion she was sold to Greyhound Leasing and began hauling containerized cargo for Seatrain Lines between U.S. west coast ports and Hawaii, Guam and other U.S. Pacific territories.
