The Perry County Courthouse is a historic government building in the city of New Lexington, Ohio, United States.

[3] Designed by Joseph W. Yost,[1] and built at a cost of $143,000,[5] the present Perry County Courthouse is a large Richardsonian Romanesque building constructed of stone; the ashlar walls are laid in a random fashion, while the ashlar of the foundation is laid in a more regular manner.

[3] The most prominent component of the exterior is the two-part clock tower in the center, which rises 40 feet (12 m) above the street, but the entire building derives an appearance of great size from its three-story construction[6] and from the large monolithic wall above the main entrance.

[3] From its earliest years, the courthouse has been considered one of Ohio's grandest,[5] due in part to its location in a small community in a rural county.

[1] In the 1990s, the courthouse attracted statewide attention when a prominent lawsuit, DeRolph v. State, was filed in the Perry County Common Pleas Court.
