The Watauga Association was a semi-autonomous government created in 1772 by frontier settlers living along the Watauga River in what is now Elizabethton, Tennessee. Although it lasted only a few years, the Watauga Association provided a basis for what later developed into the state of Tennessee and likely influenced other western frontier governments in the trans-Appalachian region. North Carolina annexed the Watauga settlement area, by then known as the Washington District, in November 1776. Within a year, the area was placed under a county government, becoming Washington County, North Carolina, in November 1777. This area covers the present day Washington County, Carter County, and other areas now located in the northeast part of the state of Tennessee.

The Watauga River is a large stream of western North Carolina and East Tennessee. It is 78.5 miles (126.3 km) long with its headwaters in Linville Gap to the South Fork Holston River at Boone Lake.
