The Ionia and Lansing Rail Road is a defunct railroad which operated in the state of Michigan in the 1860s and 1870s. The company incorporated on November 13, 1865; the investors hailed primarily from Lansing, Ionia and Portland. The original charter called for a 34-mile (55 km) line from Ionia to Lansing; on January 13, 1869 this was amended with a much grander vision: a 125-mile (201 km) line from Lansing to the mouth of the Pentwater River at Pentwater, on the shores of Lake Michigan.
