Murong Hui (慕容會) (373–397) was a general and imperial prince of the Xianbei state Later Yan, who served under his grandfather Murong Chui (Emperor Wucheng) and father Murong Bao (Emperor Huimin). During his father's reign, angry that he was not created crown prince, he tried to seize that position by force, but after his failure was killed.
Murong Hui was born to Murong Bao and a concubine described as of lowly birth while Murong Bao was a low-level Former Qin official, after Murong Chui, a Former Yan prince, had sought refuge with Former Qin's emperor Fu Jiān in 369 after a dispute with Former Yan's Empress Kezuhun and regent Murong Ping, and after Former Qin had destroyed Former Yan in 370. He was therefore probably born in the Former Qin capital Chang'an, where Murong Bao served.
When Murong Chui rebelled against Former Qin in 384 and established Later Yan, Murong Hui was in Chang'an, then still under Former Qin control. After the last Former Yan emperor Murong Wei, then a Former Qin general, tried to rebel within the city around the new year 385, Fu Jiān ordered the Xianbei in the city killed, but Murong Hui, along with his uncle Murong Rou (慕容柔) and brother Murong Sheng, were not killed, apparently because Murong Rou had been adopted by the eunuch Song Ya (宋牙). Soon thereafter, though, Murong Rou, Murong Sheng, and Murong Hui fled Chang'an and sought refuge with Murong Wei's brother and the leader of the nascent Western Yan state, Murong Chong.
Western Yan eventually captured Chang'an, but Murong Chong was killed in a coup, and the Xianbei people of the state abandoned Chang'an and began heading east back to their homeland. After a series of coups in 386, Murong Yong became emperor, and under his leadership Western Yan settled in at Zhangzi (長子, in modern Changzhi, Shanxi). In winter 386, Murong Sheng saw that they were being suspected by Murong Yong on account of their being descendants of Murong Chui, and therefore persuaded Murong Rou and Murong Hui to flee to Later Yan. It took them a year to arrive in the Later Yan capital Zhongshan (中山, in modern Baoding, Hebei), and upon arrival in the capital, Murong Hui was created the Duke of Qinghe.
