Heonan, personal name Kim Ŭijŏng, was the 47th king of the Silla kingdom of Korea. He was the younger half-brother of King Sinmu. What little we know of his reign comes from the Samguk sagi. The rebel leader Kung Ye is alleged to have been a son of either King Heonan or Gyeongmun, though the accuracy of such a claim is not fully verifiable.
