Calatayud (; 2014 pop. 20,658, declining during the last decade due to migration) is a municipality in the Province of Zaragoza, within Aragón, Spain, lying on the river Jalón, in the midst of the Sistema Ibérico mountain range. It is the second-largest town in the province after the capital, Zaragoza, and the largest town in Aragón other than the three provincial capitals. It is the seat of the comarca of Calatayud.
The city has the title Muy noble, leal, siempre augusta y fidelísima ciudad de Calatayud ("The very noble, loyal, always august and most faithful City of Calatayud"). The first democratic elections after General Franco's regime were called for 15 June 1977. In Calatayud they were held one day earlier than all the rest of Spain, in order to prepare for a visit there by King Juan Carlos I.
Calatayud is a Spanish Denominación de Origen (DO) for wines located in the southwestern corner of the province of Zaragoza ( Aragón, Spain) about 90 km from Zaragoza and covers over 5,600 ha, extending over 46 different municipalities, including Calatayud itself. It borders with the Cariñena (DO) in the east and with the province of Soria in the west. It is in the valley of the River Ebro and is crisscrossed by many other rivers including the Jalón, Jiloca, Manubles, Mesa (river), Piedra and Ribota. The vineyards are to be found on the south facing slopes of the Sierra de la Virgen range at heights of between 550 m and 800 m above sea level. Calatayud achieved DO status in 1990 and it became Aragon’s second largest quality wine-producing region after Cariñena.
