Yuwen Shu, courtesy name Botong (伯通), formally Duke Gong of Xu (許恭公), was a Chinese military general and politician of the Sui dynasty. He was a confidant of Emperor Yang and was instrumental in Yang Guang's displacement of his brother Yang Yong as crown prince; therefore, after Yang Guang became emperor, Yuwen Shu became exceedingly powerful and was one of two generals who spearheaded Yangdi's efforts in the Goguryeo-Sui Wars. His son Yuwen Huaji later led a coup against Emperor Yang in 618 and, after killing Emperor Yang, briefly claimed imperial title in 619 and founded the state of Xu, but was soon captured and killed. Another son of Yuwen Shu, Yuwen Shiji, however, was a friend of the Tang dynasty's founder Li Yuan, and after Li Yuan established Tang remained an influential official.
