Ordoño II (c. 873 – June 924, León) was a king of Galicia from 910, and king of Galicia and León from 914 until his death. He was an energetic and feisty ruler who submitted only the territories of the kingdom of Leon under his control and fought successfully against the Muslims, who still dominated most of the Iberian Peninsula. His reign marked the tactical and smooth transition of the regnum Asturum to the regnum Legionis, with the royal headquarters already established in the city of León.
