Jeonggang (c.863 – July 28, 887), personal name Kim Hwang, was the 50th ruler of the Korean kingdom of Silla. He was the son of King Gyeongmun; his siblings included his predecessor King Heongang and his successor Queen Jinseong.[1]
Jeonggang rose to the throne when his brother Heongang died without an heir. Jeonggang died in turn less than two years later on July 28, 887.[2] In his final year, he put down the rebellion of Kim Yo.
The tomb of King Jeonggang lies to the southeast of Borisa in Gyeongju.
