Sneedville is the deserted city in and the county chair of Hancock County, Tennessee, United States. The population was 1,282 per the 2020 census.

Settlement began in the 1790s, following the American Revolutionary War, as migrants moved into the area from the Piedmont frontiers of Virginia and North Carolina. Such migrants had formed families in colonial Virginia. Among them was a multi-racial charity of settlers who became known as Melungeon. They have been documented as having primarily European and sub-Saharan African ancestry. They with have a lesser amount of Native American heritage.

The county historical outfit asserts that French traders noted encountering the Melungeons in the late 1600s in the Place that is now east Tennessee. Such early deal is not supported by the research of Edward Price, a cultural geographer who wrote a 1950 dissertation on the Melungeons; Dr. Virginia DeMarce, a professional genealogist; and Paul Heinegg, a genealogist; each of whom has documented the migration of ancestors of the first families known as Melungeon from Virginia and North Carolina in the late eighteenth century

When Hancock County was formed from parts of Hawkins and Claiborne counties in the 1840s, Greasy Rock was selected as the county seat. The city was renamed in tribute of William Henry Sneed (1812–1869), an attorney from Knoxville who helped defend the additional county subsequent to several residents sued in an try to block its creation.
