Yang Xiu (died 618) was an imperial prince of the Chinese dynasty Sui Dynasty. He was a son of Emperor Wen and his wife Empress Dugu Qieluo, and during most of his father''s reign was given great control over the modern Sichuan and Chongqing region. In 602, after accusations were made that Yang Xiu was abusing his power, Emperor Wen removed him from power and reduced him to commoner rank. He was subsequently held under house arrest for the rest of Emperor Wen''s reign and the reign of his brother Emperor Yang. In 618, after the general Yuwen Huaji killed Emperor Yang, he and his coconspirators briefly considered declaring Yang Xiu emperor, but ultimately decided not to, and instead executed Yang Xiu and his sons.
