The Department of Alto Adige (Italian: Dipartimento dell'Alto Adige, French: département du Haut-Adige) was a department of Napoleon's Kingdom of Italy. It was named after the river Adige (Etsch), which flowed through it. The capital of the department was Trento.
The department's territory was not the same as that of the modern Italian province of Alto Adige. Some of the territory is the same, such as the city of Bolzano, but most of the rest is now part of the province of Trento. These two provinces form the region Trentino-Alto Adige/Südtirol.
