The Chestatee River (variant spellings Chestatie, Chestetee, Chostatee, Chosteta,Chestotee none in modern use) is a 50.8-mile-long (81.8 km) river in the Appalachian Mountains of northern Georgia, USA. It begins at the confluence of Dicks Creek and Frogtown Creek (near the junction of U.S. 19 and U.S. 129) in northeastern Lumpkin County, flowing down by the county seat and former Georgia Gold Rush town of Dahlonega, and then under the northern terminus of the Georgia 400 expressway from Atlanta. It originally continued past the southern corner of the county, forming the entire eastern border of southern Dawson County with northwestern Hall County, and the far northern part of Forsyth's border with Hall.
