Fairfield County originally encompassed all or parts of present day [update] Knox, Hocking, Licking, Perry, and Pickaway counties.  Fairfield is a descriptive name referring to the beauty of their fields. 
Fairfield County sits just on the edge of Ohio's Appalachian region. While the once-glaciated northern portion of the county is fairly flat, as one travels south along U.S. 33 one can easily recognize the foothills of a mountainous region beginning around the village of Carroll. Although not officially part of the state or federal definition of Appalachia, certain areas of Fairfield County—particularly south of U.S. 22—bear a distinctly Appalachian feel in both physical geography and demographics.
