The name was derived from the Osage Nation, whose traditional territory encompassed this area.

[4] The Little Osage rises in Kansas in northeastern Allen County at the confluence of the North and Middle Forks.

The stream meanders eastward passing north of Fulton, and under U.S. Route 69, where it enters northwestern Vernon County, Missouri.

On the boundary of Vernon and Bates counties, the Little Osage joins the Marais des Cygnes River to form the Osage River, 6 miles (10 km) west of Schell City.
