History

Formed in 1797 from Greene County and Jefferson County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Cocke County was created from Greene and Jefferson Counties on October 9, 1797, and named after William Cocke. It gained territory from Greene, Jefferson, Hamblen, and Sevier Counties through various adjustments over the following decades to accommodate local residents.
