Kim Kyemyŏng (Korean: 김계명; Hanja: 金啓明) was a member of the royal family of Silla.
He married Lady Ganghwa, the daughter of King Sinmu.
His sons were King Gyeongmun and Kim Wi-hong.
He succeeded Kim Yang as the director of the Chancellery (집사성 시중; 執事省侍中; chipsasŏng sijung).
Kim is thought to have died sometime before 866, as in 866 he was posthumously honoured as King Uigong (의공대왕; 懿恭大王) by his son.
