Conasauga Creek is a 42.8-mile-long (68.9 km) tributary stream of the Hiwassee River, located in southeast Tennessee, in the United States. It is not to be confused with the nearby Conasauga River. Conasauga Creek flows from its source in the Unicoi Range (part of the Appalachian Mountains) in Monroe County. It flows by the town of Coker Creek and, following a generally northeast route, passes between Mocking Crow Mountain and Pine Mountain to emerge into the valley of Rural Vale. From there it curves around the northern end of Starr Mountain, turning east and then southeast. Starr Mountain marks the boundary between the higher mountains of the southern Blue Ridge Mountains and the lower ridges of the Ridge-and-valley Appalachians.
