Acadia Cliffs State Nature Preserve is a state nature preserve in Washington County, Ohio, United States, with a small neck extending into Athens County, Ohio.

The nature preserve is close to the Washington-Athens County border.

The name derives from the fact that the land was formerly owned by the Acadia Coal Company.

This nature preserve was established in part to protect the Bradley's spleenwort, Asplenium bradleyi, which grows there.
