Chickasaw, OH

Chickasaw is a Mercer County village laid out in 1838 and named for the Chickasaw people. A post office opened in 1840, and the village has remained a small crossroads in western Ohio’s farm country. The 2020 census counted 358 residents. Its name connects the town to a much older Indigenous history, while the surrounding roads lead toward Celina, St. Henry, and the other Mercer County communities that share the local school, library, and agricultural network.

The Zahn-Marion Township Branch of the Mercer County District Library occupies a place given by the village in 1983, giving Chickasaw a neighborhood library with children’s programs, book groups, and internet access. The library’s history is a good example of how a small village stays tied to county institutions: the building is local, the system is regional, and residents use both. Chickasaw’s main streets, post office history, and library create a recognizable center even as farm fields take over just beyond the village line. It is a Mercer County village with a nineteenth-century beginning and a present-day routine built around nearby towns and shared services.
