The Saginaw River is a 22.4-mile-long (36.0 km)[3] river in the U.S. state of Michigan. It is formed by the confluence of the Tittabawassee and Shiawassee rivers southwest of Saginaw. It flows northward into the Saginaw Bay of Lake Huron, passing through the cities of Saginaw and Bay City, both of which developed around it in the 19th century. The watershed area is 8,595 square miles (22,260 km2).[4] At its mouth, the river's estimated average discharge is 4,827 cubic feet per second (136.7 m3/s).[5]

The river is an important shipping route for Mid-Michigan, passing through the cities of Saginaw and Bay City. It is one of Michigan's few inland navigable rivers. The Saginaw River Rear Range Light, one of a pair of lighthouses built in 1876 to improve navigation, was listed on the National Register of Historic Places in 1984. Since the turn of the 21st century, it is being renovated.
