Outer Subcarpathia (Polish: Podkarpacie Zewn?trzne; Ukrainian: , Prykarpattia; Czech: Vn?karpatské sní?eniny; German: Karpatenvorland) denotes the depression area at the outer (western, northern and eastern) base of the Carpathian arc, including foothills of the Outer Western Carpathians and Outer Eastern Carpathians. It stretches from northeastern Austria, through eastern Czech Republic, southern Poland, western Ukraine and northeastern Romania.
The western end is marked by the (northern) Vienna Basin, separating it from the Eastern Alpine Foreland. The adjacent hilly landscape of the Lower Austrian Weinviertel region with its extensive loess layers border on the limestone rock formations of the South-Moravian Carpathians.
In the Czech Republic, the depression is situated on the outskirts of the White Carpathians in Moravia, including the Pálava Protected Landscape Area. In Poland they stretch along the Lesser Poland Voivodeship to the Podkarpackie Voivodeship, part of the Galicia historic region that leads to Ukraine (Lviv, Ivano-Frankivsk and Chernivtsi Oblast) and the Dniester Basin.
