Ross County is a county in the Appalachian region of the U.S. state of Ohio. As of the 2010 United States Census, the population was 78,064. Its county seat is Chillicothe, the first and third capital of Ohio. Established on August 20, 1798, the county is named for Federalist Senator James Ross of Pennsylvania. Ross County comprises the Chillicothe, OH Micropolitan Statistical Area, which is also included in the Columbus-Marion-Zanesville, OH Combined Statistical Area.
Ross County was described by Ephraim George Squier and Edwin Hamilton Davis as having almost "one hundred enclosures of various sizes, and five hundred mounds" in their book, Ancient Monuments of the Mississippi Valley (1848). They described the Indian-built earthworks as ranging from five to 30 feet in size, and enclosures of one to 50 acres large. These included Serpent Mound, Fort Ancient, Mound City, and Seip Earthworks (both now part of Hopewell Culture National Historical Park), and Newark Earthworks. 
The Scioto River flows southward through the east-central part of the county. Paint Creek drains the lower central part of the county, flowing eastward to its terminus with the Scioto at a point southeast of Chillicothe. The county terrain consists of frequent wooded hills, with the intermediate level areas devoted to agriculture. The county's highest point is Farrell Hill, six miles (10 km) northeast of Bainbridge. The county has a total area of 693 square miles (1,790 km2), of which 689 square miles (1,780 km2) is land and 3.8 square miles (9.8 km2) (0.6%) is water. Ross County is the second-largest county by land area in Ohio, after Ashtabula County, as well as the fifth-largest by total area.
