The Grésivaudan (sometimes Graisivaudan) is a valley of the French Alps, situated mostly in the Isère. Etymologically, Graisivaudan comes from roots meaning "Grenoble" (Gratianopolis) and "valley". It comprises the alluvial plain of the river Isère from Grenoble to the confluence of the Arc; or, more recently, the entire valley of the Isère from Tullins to Albertville. The stretch from Tullins to Grenoble is the Bas-Grésivaudan (Lower Grésivaudan) and that between Grenoble and Albertville is the Haut-Grésivaudan (Upper Grésivaudan).
