King Bongsang of Goguryeo (died 300, r. 292–300) was the 14th ruler of Goguryeo, the northernmost of the Three Kingdoms of Korea. He was the eldest son of King Seocheon.

From his youth, he is said to have been arrogant and dissolute, full of mistrust and envy. As soon as he was crowned, Bongsang charged his popular uncle Go Dal-ga (Prince An-guk) with treason and had him slain, upsetting his people.

In the eighth lunar month of 293 the Xianbei chieftain Murong Hui invaded. Bongsang fled to the mountain of Sinseong. The sohyeong of the north, Go No-ja, led five hundred cavalry out to meet the king, and went on to defeat the Xianbei forces. King Bongsang promoted Go No-ja to daehyeong, a position of the 5th rank, giving him Gongnim as stipend land.

The following month, the king feared that his younger brother Go Dol-go was plotting against him, and forced him to commit suicide. Dol-go's son, the subsequent king Micheon fled and preserved his own life. In the eighth month of 296, Murong Hui invaded once more, but was repelled.

The following month, a heavy frost and hail fell and destroyed the crops, but the king carried on with reconstructing the palace with gaining massive complaints from his people. In spite of continuous resentment, King didn't listen to the counsels of his ministers, while some of Goguryeo people chose to flee away from forced labor.

In the end, his ministers carried out a coup in the eighth lunar month of 300. Bongsang and his two sons committed suicide. He was buried in Bongsan-won. The ministers found the escaped prince, and set him on the throne as King Micheon.

烽上王（？ - 300年），高句麗第14任君王，名相夫、歃矢婁，292年-300年在位。

293年八月，慕容鮮卑首領慕容廆率軍攻打高句麗，烽上王狼狽奔逃，手下五百騎死戰抵擋了慕容廆的追兵。

由于擔心其弟高咄固與他爭權，烽上王將其弟逼死。其弟的兒子乙弗逃走，後來成為美川王。

296年，慕容廆再次攻打高句麗，西川王（西壤王）的陵墓被挖，並擄去烽上王的生母。但後來被高句麗擊退。

烽上王在位期間，乾旱、地震、霜降等異常氣候導致了百姓生活困頓不堪，烽上王在外有鮮卑慕容家族崛起的憂患之下，還加修宮殿等嚴重的奢侈行為。且不聽賢臣進諫，為了維護君王的威嚴，還把百姓抓來充當勞役。

高句麗名臣倉助利等眾大臣一起商議廢除君主，推舉了烽上王的侄子乙弗，輔佐他做了美川王。

烽上王知道民心的離背後自殺身亡。
