The National University of the Chaco Austral (Universidad Nacional del Chaco Austral - UNCAus) is a very recently established national university located in Sáenz Peña, a city in the agrarian, central section of Chaco Province, Argentina. It was established in 2007 by an initiative of Governor Jorge Capitanich, and was included as part of a plan to geographically diversify Argentina's National University system; as such, its installations consist of the former local campus of the National University of the Northeast, notably the School of Agronomy and Forestry, and new additions.
