Clingman's Dome is a mountain in the Great Smoky Mountains of Tennessee and North Carolina, in the southeastern United States. At an elevation of 6,643 feet, it is the highest mountain in the Smokies, the highest point in the state of Tennessee, and the highest point along the 2,174-mile Appalachian Trail.

The concrete observation tower, built in 1959, offers a panoramic view of the mountains in every direction. An air quality monitoring station, operated by the Environmental Protection Agency, is the second highest in eastern North America.
