Ordoño I (c. 821 – 27 May 866) was King of Asturias from 850 until his death. He was born in Oviedo, where he spent his early life in the court of Alfonso II. He was probably associated with the crown from an early age. He was probably raised in Lugo, capital of the province of Galicia, of which his father, Ramiro, had been named governor. There he was educated, including in the military arts. Ordoño married Muniadona. He had six children, including his successor, Alfonso III. Ordoño died in Oviedo and was succeeded by his eldest son.
