Haute Vallée de Chevreuse Regional Natural Park (French: Parc naturel régional de la haute vallée de Chevreuse) is a protected area in the Île-de-France region of northern France. It is a verdant rural area outside Paris, designated as a regional natural park because it contains a wide variety of unique historical sites.
The parkland spans two departments, Yvelines and Essonne, and connects fifty-one separate communes along the Chevreuse valley of the river Yvette. The park's main office is located in Chevreuse in a medieval fortress, the Château de la Madeleine.
The land was officially designated as a parc naturel régional (PNR) in 1985, with a total area of 25,600 hectares (63,000 acres).
