There are two former counties in Tennessee:

• James County (1870–1919) - Now part of Hamilton County. The county seat was Ooltewah.
• Tennessee County (1788–1796) - When Tennessee achieved statehood, the previous Tennessee County in North Carolina became Tennessee County, Tennessee, and was divided into Montgomery and Robertson Counties.

Three Tennessee counties operate under consolidated city-county governments, a city and county that have been merged into one jurisdiction. As such, these governments are simultaneously a city, which is a municipal corporation, and a county, which is an administrative division of a state.

• City of Nashville and Davidson County
• City of Lynchburg and Moore County
• City of Hartsville and Trousdale County
