The Fort Ancient culture is a Native American archaeological culture that dates back to c. 1000–1750 CE. Members of the culture lived along the Ohio River valley, in an area running from modern-day Ohio and western West Virginia through to northern Kentucky and parts of southeastern Indiana. A contemporary of the neighboring Mississippian culture, Fort Ancient is considered to be a separate "sister culture". Mitochondrial DNA evidence collected from the area suggests that the Fort Ancient culture did not directly descend from the older Hopewell Culture.
Fort Ancient is a Native American earthworks complex located in Washington Township, Warren County, Ohio, along the eastern shore of the Little Miami River about seven miles (11 km) southeast of Lebanon on State Route 350. The site is the largest prehistoric hilltop enclosure in the United States with three and one-half miles (18,000 ft) of walls in a 100-acre (0.40 km2) complex. Built by the Hopewell culture, who lived in the area from the 200 BC to AD 400, the site is situated on a wooded bluff 270 feet (82 m) above the Little Miami. It is the namesake of a culture known as Fort Ancient who lived near the complex long after it was constructed.

The Newark Earthworks in Newark and Heath, Ohio, consist of three sections of preserved earthworks: the Great Circle Earthworks, the Octagon Earthworks, and the Wright Earthworks. This complex, built by the Hopewell culture between 100 BCE and 400 CE, contains the largest earthen enclosures in the world, and was about 3,000 acres (1,200 ha) in total extent.

A designated National Historic Landmark, in 2006 the Newark Earthworks was also designated as the "official prehistoric monument of the State of Ohio."
