Originally called "Laurel Gap", the area was first settled in 1776. Many Families lived in Laurel Gap mostly farmers. Then a name change came about and it was called Bailey Town from 1892 until 1915. When the town became incorporated in 1915, the w was dropped and the name changed to "Baileyton", which stems from Claudius and Thomas P. Bailey, two brothers who lived there.

Baileyton is located the base of a rugged area of northern Greene County, just south of the Hawkins County line.

The town is drained primarily by Gardner Creek and Hughes Branch, both tributaries of Lick Creek (which is in turn a tributary of the Nolichucky River).
