Washington County is a county located in the U.S. state of Tennessee. As of the 2010 census, the population was 122,979. Its county seat is Jonesborough. The county's largest city and a regional educational, medical and commercial center is Johnson City. Washington County is Tennessee's oldest county, having been established in 1777 when the state was still part of North Carolina.
Washington County is part of the Johnson City, TN Metropolitan Statistical Area, which is a component of the Johnson City–Kingsport–Bristol, TN-VA Combined Statistical Area, commonly known as the "Tri-Cities" region.
Washington County is rooted in the Watauga settlements, which were established in the early 1770s in the vicinity of what is now Elizabethton, in adjacent Carter County. At the outbreak of the Revolutionary War in 1776, the Wataugans organized the "Washington District," which was governed by a committee of safety. North Carolina initially refused to recognize the settlements as legal, but finally agreed to annex the district after the settlers thwarted an invasion by hostile Cherokees. The settlements were governed as the Washington District, which originally included all of what is now Tennessee. The district was reorganized as Washington County in 1777.
