Swiftstar was a steam tanker built in 1920-1921 by Northwest Bridge & Iron Company of Portland for the Swiftsure Oil Transport Co., a subsidiary of the France & Canada Steamship Co., with intention of transporting oil from foreign ports to refineries along the Gulf and East Coasts of the United States. The ship had short but troubled history. In July 1923 after departing Colón the tanker went missing. Large oil slick, burnt remnants and several lifeboats bearing the ships's name were later found indicating the ship exploded. All 32 people on board were presumed lost.
