Prévost is a town within the La Rivière-du-Nord Regional County Municipality, Quebec, Canada, and the administrative region of Laurentides in the Laurentian Mountains, north of Montreal. It was created in 1973 from the amalgamation of the former villages of Shawbridge and Lesage with old Prévost on the other side of the Rivière du Nord. Shawbridge was named after William Shaw (1805-1894) who settled in the township of Abercromby in 1847 and built the first bridge over the Rivière du Nord. Prévost was formerly known as Shawbridge until 1973.
