Tordesillas (Spanish pronunciation: [toɾðeˈsiʎas]) is a town and municipality in the province of Valladolid, Castile and León, central Spain. It is located 25 kilometres (16 mi) southwest of the provincial capital, Valladolid at an elevation of 704 m (2,310 ft). The population was c. 8,760 as of 2021.
The town is located on the Douro River although the river is not navigable at that point. Highways connect to Madrid (182 km (113 mi) southeast) and Salamanca (96 km (60 mi) southwest). The provincial capital Valladolid is also linked by four-lane highway. Because of its important highway connections Tordesillas has become a major transit hub. The economy is based on services—especially connected to tourism—and the agricultural production of the surrounding area. Wheat has long been the traditional agricultural product (see Cuisine of the province of Valladolid).
