Xiao Zhuang (蕭莊) (548-577?), often known by his princely title of Prince of Yongjia (永嘉王), was a grandson of Emperor Yuan of Liang, who was declared by the general Wang Lin to be the legitimate emperor of Liang Dynasty in 558, under military assistance by Northern Qi. He thus was one of the three claimants to the Southern dynasties throne, competing with Emperor Xuan of Western Liang, who was supported by Northern Zhou, and Chen Dynasty's founder Emperor Wu of Chen and later his nephew Emperor Wen of Chen. In 560, with Wang Lin defeated by Chen troops, both Wang and Xiao Zhuang fled to Northern Qi, ending their rivalry with Chen and Western Liang. While Northern Qi emperors made promises to return Xiao Zhuang to the Liang throne, Northern Qi was never able to accomplish that promise, and Xiao Zhuang died shortly after Northern Qi's own destruction in 577.
