Ordoño II (c. 873–924, León) is a king of Galicia from 910, and king of Galicia and León from 914 until his death.

He is an energetic and feisty ruler who submits only the territories of the kingdom of Leon under his control and fights successfully against the Muslims, who still dominate most of the Iberian Peninsula.

His reign marks the tactical and smooth transition of the regnum Asturum to the regnum Legionis, with the royal headquarters already established in the city of León.
