Clinch Mountain is a mountain ridge in the U.S. states of Tennessee and Virginia, lying in the ridge-and-valley section of the Appalachian Mountains. From its southern terminus at Kitts Point, which lies at the intersection of Knox, Union and Grainger counties near Blaine, Tennessee, it runs in a generally east-northeasterly direction to near Burke's Garden, Virginia. It separates the Clinch River basin, to the north, and the Holston River basin, to the south.
