The Little Osage River is an 88-mile-long (142 km) 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, whose traditional territory encompassed this area.
