State Route 257 (SR 257) is a southwest–to–northeast state highway located in the central part of the U.S. state of Georgia. It travels from Cordele to Dublin, via Hawkinsville. Its routing is located within portions of Crisp, Dooly, Wilcox, Pulaski, Bleckley, Dodge, and Laurens counties. SR 257 was the basis for a proposed connector route for I-75, Interstate 175 that would have connected Albany and Cordele on a more easterly routing.
