Kim Yang (Korean: 김양; Hanja: 金陽; 808–857) was part of the Silla royal family and its retainers.
Kim Yang, who was then concealing himself on a mountain near the capital, heard the news and raised up an army to go to Cheonghaejin.
U-jing and Kim Yang asked Jang Bogo to help him to take advantage of the confusion of the country and to make himself a king.
Jang Bogo agreed and had his friend Jeong Nyeon also follow Ujing.
In 839, U-jing, Kim Yang and their followers defeated King Minae's army at the battle of Daegu and quickly advanced upon the capital.
