SS Choctaw was a steel-hulled American freighter in service between 1892 and 1915, on the Great Lakes of North America. She was a so-called monitor vessel, containing elements of traditional lake freighters and the whaleback ships designed by Alexander McDougall. Choctaw was built in 1892 by the Cleveland Shipbuilding Company in Cleveland, Ohio, and was originally owned by the Lake Superior Iron Company. She was sold to the Cleveland-Cliffs Iron Company in 1894 and spent the rest of her working life with it. On her regular route between Detroit, Escanaba, Marquette (all in Michigan), and Cleveland, she carried iron ore downbound, and coal upbound.
