Washington County is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 133,001. 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–KingsportBristol, 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.

From 1784 through 1788, the county was part of the State of Franklin, an early attempt to create a fourteenth state prior to Kentucky and Vermont's admissions into the union. It then became part of the Southwest Territory in 1790, and finally, part of Tennessee after it was admitted to the Union in 1796 as the 16th state. Jonesborough, the county seat of Washington County, is Tennessee's oldest town. With many buildings restored, it comprises one of the nation's most authentic historic districts of the period 1790–1870.

Washington County was divided between pro-Union and pro-secession sentiments at the outset of the Civil War. In Tennessee's Ordinance of Secession referendum on June 8, 1861, Washington Countians voted 1,445 to 1,022 in favor of remaining in the Union. One of the bridges targeted by the East Tennessee bridge-burners in November 1861 was located in what is now Watauga near the Washington-Carter county line. Landon Carter Haynes, a Confederate senator, hailed from Washington County.

Johnson City, originally known as Johnson's Depot, was a major railway center for the southeastern states, connecting the region for freight transportation and passengers. It was the headquarters for both the standard-gauge Carolina, Clinchfield, and Ohio (Clinchfield Railroad), which required the excavation and blasting of 17 tunnels during its construction; and the narrow-gauge East Tennessee and Western North Carolina Railroad (Tweetsie). Significant restoration is underway, as well as publicizing the railroad heritage of the Johnson's Depot Historic District. Other historic properties are being restored as representative of Johnson City's late nineteenth and early twentieth-century era as a railway center.

According to the U.S. Census Bureau, the county has a total area of 330 square miles (850 km2), of which 326 square miles (840 km2) is land and 3.3 square miles (8.5 km2) (1.0%) is water. The western portion of the county is situated in the Ridge-and-Valley Appalachians, which are characterized by long, narrow ridges roughly oriented northeast-to-southwest. The county's most prominent Ridge-and-Valley features rise in the vicinity of its northwestern border with Hawkins and Sullivan counties. The eastern portion of the county lies within the Blue Ridge Mountains, specifically the Bald Mountains (south of the Nolichucky River) and the Unaka Range (north of the Nolichucky). Buffalo Mountain, a long ridge that straddles much of Washington's eastern boundary, contains the county's highest point, 3,520-foot (1,070 m) Pinnacle Knob. The Cherokee National Forest protects much of the extreme eastern part of the county. Sampson Mountain, which rises in the southeastern part of the county, is home to a designated national wilderness area.

The Nolichucky River flows through the southern part of Washington County. The Watauga River flows the northern part of the county, and forms part of the county's border with Sullivan County. The lower section of the Watauga River is part of Boone Lake.
