The Barnesville Petroglyph petroglyph site in the eastern part of the U.S. state of Ohio. Located approximately southwest of the village of Barnesville in Belmont County, the petroglyphs have been known both by archaeologists and the general public since the 1850s or earlier. Although the site was significantly damaged during the twentieth century, it is still a significant archaeological site, and has been named a historic site.
The Barnesville Petroglyph carvings were created centuries ago by Native American people. The precise cultural affiliation of its creators is uncertain. Some have attributed the site to the Adena, who inhabited the region approximately between 500 BC and AD 300. However, Barnesville shares many similarities with other petroglyph sites in western Pennsylvania, northern West Virginia, and other parts of eastern Ohio; as a result, petroglyph specialist James L. Swauger concluded that it was the work of the people that also created such sites
