The Southtowns (also known as the Buffalo Southtowns, the South Towns, or Southtown) is a region of Western New York, United States, that lies within the snowbelt or ski country and includes the southern suburbs of Buffalo, New York. This is the common name for the southern part of Erie County, New York which served as the home of United States President Millard Fillmore. The region has numerous historic landmarks, especially in Springville and East Aurora.

According to a telephone directory that formerly published specific editions for the area, this region includes Aurora, Blasdell, East Aurora, Elma, Hamburg, and Orchard Park. Several other towns in the snowbelt south of Buffalo are also considered part of the Southtowns. According to one source the entire southern part of Erie County, West Seneca and southward are part of the Buffalo Southtowns. This region is the northwesternmost foothills of the Appalachian Mountains. The New York State Department of Transportation's Scenic Byways Advisory Board created Western New York's first Scenic Byway, WNY Southtowns Scenic Byway, which travels through the townships of Orchard Park, Boston, Concord, Colden and Aurora, the three villages of Orchard Park, Springville and East Aurora and several rural hamlets including the hamlets of Boston and Colden. The National Weather Service defines the Southtowns (forecast zone NYZ085, "Southern Erie County") as anything south of U.S. Route 20A. The region includes the northeastern half of the village of Gowanda, but not the southwestern half.
