The St. Joseph River (Miami-Illinois: Kociihsasiipi) is an 86.1-mile-long (138.6 km) tributary of the Maumee River in northwestern Ohio and northeastern Indiana in the United States, with headwater tributaries rising in southern Michigan. It drains a primarily rural farming region in the watershed of Lake Erie.
The St. Joseph River of Lake Michigan is an entirely separate river that rises in western Michigan, dips into Indiana, and flows west into Lake Michigan.
