The Unaka Range is a mountain range on the border of Tennessee and North Carolina, in the southeastern United States. It is a subrange of the Appalachian Mountains and is part of the Blue Ridge Mountains physiographic province. The Unakas stretch approximately from the Nolichucky River to the south to the Watauga River to the north. The Unakas include the prominent Roan Highlands, where several summits rise above 6,000 feet. The Iron Mountains border the Unakas to the north, and the Bald Mountains border the Unakas opposite the Nolichucky to the south.
