The amber darter (Percina antesella) is a small, endangered freshwater fish in the perch family. It is native to the Conasauga River and Etowah River in Georgia and Tennessee in the United States. It typically inhabits riffle areas over gravel and sand bottoms, hiding in aquatic vegetation when present. It feeds on small invertebrates and probably breeds between late fall and early spring. It is an uncommon fish with a small range and the International Union for Conservation of Nature has classified its conservation status as being "endangered".
