The Reichsgau Tirol-Vorarlberg (English: Gau Tyrol-Vorarlberg) was an administrative division of Nazi Germany consisting of Vorarlberg and North Tyrol (both in Austria). It existed from 1938 to 1945. After the Italian Armistice with the Allies the Italian provinces of Belluno, South Tyrol and Trentino were placed under direct German control as the Operational Zone of the Alpine Foothills (Operationszone Alpenvorland, OZAV), which was de facto annexed and administered as part of Tirol-Vorarlberg.
