Su Wei (蘇威; 542–623), courtesy name Wuwei (無畏), was a Chinese politician of the Chinese Sui dynasty.[1] He first became an important official during the reign of Sui's founder Emperor Wen,[2] and after Emperor Wen's death continued to serve Emperor Wen's son Emperor Yang. He was often praised for his abilities and integrity but criticized for pettiness.[1] After Emperor Yang was assassinated in 618, he was nominally an official under Emperor Yang's nephew Yang Hao,[3] and then under the warlords Yuwen Huaji, Li Mi, and Wang Shichong. After Wang Shichong's state of Zheng was destroyed by Tang dynasty in 621,[4] neither the Tang general Li Shimin (the later Emperor Taizong) nor Li Shimin's father Emperor Gaozu of Tang was interested in retaining Su as an official, and Su Wei died soon thereafter.[4]
