Troyes is a commune and the capital of the department of Aube in the Grand Est region of north-central France. It is located on the Seine river about 140 km (87 mi) south-east of Paris. Troyes is situated within the Champagne wine region and is near to the Orient Forest Regional Natural Park.

In the administrative divisions of France, the department is one of the three levels of government under the national level, between the administrative regions and the communes. Ninety-six departments are in metropolitan France, with an additional five constituting overseas departments, which are also classified as overseas regions. Departments are further subdivided into 333 arrondissements and 2,054 cantons. These last two levels of government have no political autonomy, instead serving as the administrative basis for the local organisation of police, fire departments as well as, in certain cases, elections.
