Ille-et-Vilaine (French pronunciation: [i.l‿e.vi.lɛn]; Breton: Il-ha-Gwilen) is a department of France, located in the region of Brittany in the northwest of the country.

Ille-et-Vilaine is one of the original 83 departments created during the French Revolution on March 4, 1790. It was created from part of the province of Brittany.

Ille-et-Vilaine is a part of the current region of Brittany and is bordered by the departments of Manche to the north-east, Mayenne to the east, Maine-et-Loire to the south-east, Loire-Atlantique to the south, Morbihan to the south-west, and Côtes-d'Armor to the west and north-west. Also the English Channel (locally named la Manche in French) borders the department to the north.

The department is named after its two main rivers, the Ille and the Vilaine, whose confluence is in Rennes, the capital of the department and of the region. Other important rivers include :

The department is moderately elevated above the level of the sea, with many hills; however the central part has a dense network of many tributaries to the Ille or the Vilaine from all around the large basin of Rennes. The elevated hills bordering this basin are covered by several old forests now exploited by men for the production of wood. The basin itself is a rich agriculture area, as well as the north-west of the department near the Rance.
