The Grand River is a river that stretches from northernmost tributary origins between Creston and Winterset in Iowa approximately 226 miles (364 km)[3] to its mouth on the Missouri River near Brunswick, Missouri.

Its watershed of 7,900 square miles (20,000 km2), with three-quarters in Missouri, makes it the largest watershed serving the Missouri River in northern Missouri.[4]
