Tudela is a municipality in Spain, the second largest city of the autonomous community of Navarre and twice a former Latin bishopric. Its population is around 35,000. The city is sited in the Ebro valley. Fast trains running on two-track electrified railways serve the city and two freeways join close to it.

Navarre, officially the Chartered Community of Navarre, is a landlocked foral autonomous community and province in northern Spain, bordering the Basque Autonomous Community, La Rioja, and Aragon in Spain and Nouvelle-Aquitaine in France. The capital city is Pamplona. The present-day province makes up the majority of the territory of the medieval Kingdom of Navarre, a long-standing Pyrenean kingdom that occupied lands on both sides of the western Pyrenees, with its northernmost part, Lower Navarre, located in the southwest corner of France.
