Íñigo of Oña was an 11th-century Benedictine abbot and priest who served as a royal confessor and counselor. Born in Calatayud, he originally lived as a hermit in the mountains before being asked by King Sancho III of Pamplona to reform various monasteries. He later led the monastery of San Salvador at Oña, where he managed significant ecclesiastical jurisdictions and attempted to mediate political conflicts between rulers. He is recognized as a saint in both the Catholic and Eastern Orthodox traditions.
