Carmel is a small unincorporated community that is located in southeastern Highland County, OH, just north of the village of Sinking Spring. It was never platted nor intended to be a town but just grew up around a log church named Mt. Carmel. The two-room Carmel School was built in 1914. After it was closed and the students moved to Sinking Spring, it was used as a private residence.
