Murong Yao (Chinese: 慕容瑤; died 386), also known as Murong Wang (慕容望), was an emperor of the Xianbei-led Western Yan dynasty of China.
He was the son of Murong Chong (Emperor Wei), the son of the Former Yan emperor Murong Jun.
Murong Chong was killed in 386 by his general, Han Yan (韓延) after he, against his people's desire to return to their homeland, wanted to settle in Chang'an.
However, the people did not favor Murong Yao.
They abandoned him in favor of general Murong Yong, who then killed Murong Yao in a coup and replaced him with Murong Zhong, the son of Western Yan's founder Murong Hong the Prince of Jibei.
