Heonan (died 861), personal name Kim Ŭi-jŏng, was the 47th king of the Silla kingdom of Korea.
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.
[1][2] Following a famine in the year 859, he sent relief to the peasants and supported agriculture through the construction of irrigation works.
Being without a son, Heonan chose his relative Kim Ŭng-nyŏm as his heir.
After his death, Kim Ŭng-nyŏm took the throne, becoming King Gyeongmun.
