Muskegon River is a river in the western portion of the lower peninsula of the U.S. state of Michigan. The river source is located at Houghton Lake in Roscommon County, flowing out of the North Bay into neighboring Missaukee County. The river passes through Clare County, Osceola County, Mecosta County, Newaygo County, and Muskegon County, and generally flows southwesterly to its mouth at Muskegon, Michigan, where it empties into Muskegon Lake.

The primary river channel is 216 miles (348 km) long and drains an area of 2,350 square miles (6,100 km2).In September 2002, an article in National Geographic raised concerns about
