The Marine Transport Line (MTL) of New York, New York was a commercial steamship service started to support the needs of support charter shipping for the Maritime Commission and War Shipping Administration during World War II by CD Mallory & Co.^[1] During wartime the Marine Transport Line operated Victory ships, and also a few other ships.

After the war it moved to operating mostly tanker ships.^[1]^[2]^[3]^[4] MTL was acquired by the General American Transportation Company in 1970, which spun it off in 1983.^[5] In 1998, it became part of the Marine Transport Corporation, which was acquired by Crowley Maritime in 2001.

MTL experienced major incidents with its converted tanker fleet, including the 1963 disappearance of the SS Marine Sulphur Queen and the 1983 sinking of the SS Marine Electric, both converted World War 2 tanker ships.^[6]^[7]^[8]^[9]
