The Treaty of Tudilén (or Treaty of Tudején) was signed between Alfonso VII of León and Castile and Ramon Berenguer IV, Count of Barcelona in 1151 at Tudilén, near Aguas Caldas in Navarre, modern Baños de Fitero, then just Fitero. The pact recognised the Aragonese conquests south of the Júcar and the right to expand in and annex the kingdom of Murcia, save the castles of Lorca and Vera. The treaty was superseded by the Treaty of Cazola in 1179.
