Prudentius of Tarazona was a 6th-century Basque cleric and anchorite who served as the bishop of Tarazona. Born in Armentia, he began his religious life as a hermit near Soria under the guidance of Saturio. After moving to Calahorra and later Tarazona, he rose through the ecclesiastical ranks to become an archdeacon and eventually the bishop. He is recognized as a saint and serves as the patron of both Álava and Nájera.
