The Colorado River (Spanish: Río Colorado, Spanish pronunciation: [ˈri.o koloˈɾaðo]) is a river in the center of Argentina.
The Colorado River marks most of the political boundary between the Argentine provinces of Neuquén and Mendoza, and between Rio Negro and La Pampa. Its man-made dam, "Embalse Casa de Piedra," serves both to generate hydroelectricity for the arid region the river traverses, and to regulate the river's water level.
