The Little Osage River is an 88-mile-long (142 km)[3] tributary of the Osage River in eastern Kansas and western Missouri in the United States. Via the Osage and Missouri rivers, it is part of the watershed of the Mississippi River.

The name was derived from the Osage Nation.[4]


The Little Osage rises in Kansas in northeastern Allen County at the confluence of the North and Middle Forks. The stream flows southeast into Bourbon County where the South Fork joins the stream and the stream turns and flows to the east. The stream turns sharply south and crosses Kansas 65 to the east of Xenia. The stream meanders eastward passing just north of Fulton crossing under U.S. Route 69 and enters southwestern Vernon County, Missouri. In Vernon County the stream passes just north of Stotesbury and on to pass under U.S. Route 71 north of Horton and through the Four Rivers Conservation Area and is joined by the Marmaton River. 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.[5] The area to the east of the Marmaton River confluence are within the Harry S Truman Reservoir flooded area.[6]
