(Ohio)
Rockbridge State Nature Preserve is a nature reserve featuring a natural bridge located in the unincorporated community of Rockbridge in Hocking County, Ohio, United States. It is part of the Hocking Hills region, but the sandstone that forms the natural bridge is located lower in the stratigraphic sequence than that which forms most of the region's notable features.
