Huigang of Silla (died 838; r. 836–838) was the 43rd ruler of the Korean kingdom of Silla. He was the grandson of King Wonseong and the son of Kim Heon-jeong by Lady Podo. He married Lady Munmok, who was the daughter of [1] Chunggong.[2]
After the death of King Heungdeok in 836, Huigang and his uncle (Heungdeok's younger cousin) Kim Gyunjeong struggled for power.[3] After Kim Myeong (who later became King Minae) killed Kim, Huigang rose to the throne.[4]
Huigang made Kim Myeong his Sangdaedeung,[5] but the next year Kim rebelled against him.[6] Huigang killed himself, and was buried on Sosan mountain in Gyeongju.[7]
