# Clay Center, Ohio

Clay Center is a village in Ottawa County, Ohio, United States. The population was 262 at the 2020 census.

## History

Clay Center derives its name from originally being the center of a larger Clay Township. When Ottawa County was founded in 1840, Allen Township did not exist, but was the northern half of a larger Clay Township. When the Townships split in 1888, Clay Center became a part of Allen Township.
The town was founded by William Clark, a land speculator who believed a town in the center of the large township would be more likely to grow than the southern population center, Genoa. In 1883 Clay Township and Genoa discussed building a new Town Hall, and it was decided that Clay Township would help construct the building in downtown Genoa, instead of the geographic center in Clay Center. Local tradition states that this was the reason for Clay Township splitting in two a few years later.
