Somerset is a village in Perry County, Ohio, United States.

It is located 9.5 miles north of the county seat New Lexington and has a dedicated historical district.

Ten years later, a permanent courthouse was constructed on the village's public square.

From 1851 to 1859, the state legislature passed three separate laws to permit the county seat to be moved; contentious elections and a decision by the Supreme Court of Ohio saw the county seat move to New Lexington, back to Somerset, and finally back to New Lexington.
