Ordoño IV was a king of León, a historical kingdom in the northwest of the Iberian Peninsula, who reigned from 958 to 959. He was a member of the Asturian royal family and succeeded his father, Ordoño III. His reign was brief and marked by internal conflicts and challenges from rival factions. During his short rule, Ordoño IV faced opposition from nobles and was eventually overthrown. After his deposition, he disappeared from historical records, and his reign is often overshadowed by the more prominent kings of the Kingdom of León.
