The Prairie Creek Site is an archaeological site in the southwestern part of the U.S. state of Indiana. Located approximately 3 miles (4.8 km) north of Washington in Daviess County, it lies along the southern bank of the westward-flowing Prairie Creek, a White River tributary. About 1 mile (1.6 km) to the east of the site, the stream leaves the Thousand Acre Woods, a heavily wooded area around a glacial lake; six miles downstream is the creek's confluence with the White River.:65
