The Southern Limestone Alps ({{langx|it|Alpi Sud-orientali}}, {{langx|de|Südliche Kalkalpen}}), also called the Southern Calcareous Alps, are the ranges of the Eastern Alps south of the Central Eastern Alps mainly located in northern Italy and the adjacent lands of Austria and Slovenia. The distinction from the Central Alps, where the higher peaks are located, is based on differences in geological composition. The Southern Limestone Alps extend from the Sobretta-Gavia range in Lombardy in the west to the Pohorje in Slovenia in the east.
