The Little Niangua River is a 64.4 mi tributary of the Niangua River in the Ozarks region of central Missouri in the United States. Via the Niangua, Osage and Missouri rivers, it is part of the watershed of the Mississippi River. The Little Niangua was so named for its smaller size relative to the Niangua River.

Description

The Little Niangua rises in Dallas County and flows generally northeasterly through Hickory and Camden counties. It joins the Niangua River in Camden County as an arm of the Lake of the Ozarks, which is formed by a dam on the Osage River.
