The Saginaw and Mount Pleasant Railroad was a wholly owned subsidiary of the Flint and Pere Marquette Railroad (F&PM), established by the latter to construct a 14.7 miles (23.7 km) railway line between Mount Pleasant, Michigan and Coleman, Michigan. The line opened on December 15, 1879, as a 3 ft (914 mm) narrow gauge line. In mid-1884 the line was converted to 4 ft 8 1⁄2 in (1,435 mm) standard gauge. On January 31, 1889 the company was formally merged into the F&PM along with the East Saginaw and St. Clair Railroad, the Saginaw and Clare County Railroad, and the Manistee Railroad.
In 1979 the C&O abandoned the line.
