Trento, also known in English as Trent, is a city on the Adige River in Trentino-Alto Adige/Südtirol in Italy. It is the capital of the autonomous province of Trento. In the 16th century, the city was the location of the Council of Trent. Formerly part of Austria and Austria-Hungary, it was annexed by Italy in 1919. With 118,142 inhabitants, Trento is the third largest Italian city in the Alps and second largest in the historical region of Tyrol.

The Adige is the second-longest river in Italy, after the Po. It rises near the Reschen Pass in the Vinschgau in the province of South Tyrol, near the Italian border with Austria and Switzerland, and flows 410 kilometres (250 mi) through most of northeastern Italy to the Adriatic Sea.
