Södermanland (Swedish pronunciation: [ˈsø̂ːdɛrmanˌland] or [ˈsø̌ː-] ), locally Sörmland, sometimes referred to under its Latinized form Sudermannia or Sudermania, is a historical province (or landskap) on the south eastern coast of Sweden. It borders Östergötland, Närke, Västmanland and Uppland. It is also bounded by lake Mälaren and the Baltic Sea.

Södermanland means "(The) Land of the Southern Men", where the "southern men" (södermännen) were the people living south of Uppland.
