Curarrehue (Spanish pronunciation: [kuɾaˈrewe]) is a town and commune in Cautín Province of Araucanía Region, Chile. The origin of Curarrehue dates back to the occupation of Araucanía and the Conquest of the Desert by the Chilean and Argentine army respectively in the 1870s and 1880s when Mapuches were pushed by the Argentine Army through Mamuil Malal Pass into the valley of Curarrehue where they settled.
