The Grand River is a river in the Lower Peninsula of the U.S. state of Michigan. It is the longest river in Michigan.[1] Its largest city is Grand Rapids.
The river flows in a northwest direction from Hillsdale County into Lake Michigan near the city of Grand Haven. The river flows through a number of cities, including Jackson, Lansing and Ionia.
The original name for the river was "owashtanong", meaning "far-flowing water" in Ottawa.[2][3]
