The South Tyrolean Unterland (German: Südtiroler Unterland) or Bozen Unterland (Bozner Unterland; Italian: Bassa Atesina) is a section of the Etschtal valley stretching from the regional capital Bolzano (Bozen) down the Adige (Etsch) river to Tramin and Salorno (Salurn). The area is known for its viticulture; the Gewürztraminer grape originated here.
The region should not be confused with the Tyrolean Unterland in the Austrian state of Tyrol.
The Adige valley between the Fiemme Mountains in the east and the Nonsberg Group in the west is part of an important north-south transport route, traversed by the Brenner Autobahn (Autostrada A22, part of the European route E45) and the Brenner Railway line from Innsbruck to Verona.
The South Tyrolean Unterland comprises the valley municipalities of Auer, Bronzolo, Kurtatsch, Kurtinig, Laives, Margreid, Montan, Neumarkt, Salorno, Tramin, and Vadena as well as the mountain communities of Aldein, Altrei in the Fiemme Valley, and Truden. Neumarkt usually rates as the chief town of the Unterland area, though the largest settlement is Laives (Leifers). The adjacent municipalities of Eppan and Kaltern in the west, beyond the Mitterberg massif, form the separate Überetsch area. Both are part of the South Tyrolean Überetsch-Unterland district.
