The Oostanaula River (pronounced "oo-stuh-NA-luh") is a principal tributary of the Coosa River, about 49 miles (79 km) long,[2] formed by the confluence of the Conasauga and Coosawattee in northwestern Georgia in the United States.

Folklore explanations for its name state that Oostanaula is derived from a Cherokee language term meaning "rock that bars the way".

Other similar explanations include "shoally river",[3] and "a rock ledge across a stream".

The Oostanaula River is formed in northern Gordon County, Georgia, by the confluence of the Conasauga and Coosawattee rivers, and flows generally south-southwestwardly through Gordon and Floyd counties, past the towns of Resaca and Calhoun.
