The Aragón (Spanish: Río Aragón; Basque: Aragon Ibaia) is a 197 km long river in northern Spain, one of the left-hand tributaries of the river Ebro. It rises at Astún (province of Huesca) in the central Pyrenees Mountains, passes southwest through Jaca and Sangüesa (Navarre), and joins the Ebro at Milagro (Navarre), near Tudela. The name Aragón is related to the birth area of the former kingdom, which corresponds to the modern autonomous community of Aragón in Spain.
