The Cathedral of Saint Mary of Tudela (Spanish: Catedral de Santa Maria) is a Roman Catholic cathedral located in Plaza Vieja in the center of Tudela, autonomous community of Navarre, Spain.

In the aftermath of the conquest, Muslims were forced to live in a suburb outside the city walls.

The main chapel has a retablo (reredos) by 15th-century artists consisting of 18 panels of the Life of Jesus and Mary, and others depicting prophets and apostles.

The central choir was completed by Esteban de Obray in Gothic style.
