'Manistee is a city in the U.S. state of Michigan. As of the 2000 census, the city population was 6,586. It is the county seat of Manistee County. The name "Manistee" is from an Ojibwe word first applied to the principal river of the county. The derivation is not certain, but it may be from ministigweyaa, "river with islands at its mouth". Other sources claim that it was an Ojibwe term meaning "spirit of the woods. " Manistee Township is located to the northeast of the city, but is politically separate. The city is located at the mouth of the Manistee River on Lake Michigan.
