长孙无忌
Li Daozong () (603?-656?), courtesy name Chengfan (), was an imperial prince of the Chinese dynasty Tang Dynasty. He was a cousin of Emperor Taizong, and in Emperor Taizong's reign commanded forces in campaigns against Eastern Tujue, Tuyuhun, Goguryeo, and Xueyantuo. In 653, during the reign of Emperor Taizong's son Emperor Gaozong, Li Daozong offended Emperor Gaozong's uncle, the powerful chancellor Zhangsun Wuji, and Zhangsun exiled him to Xiang Prefecture (roughly modern Laibin, Guangxi), on accusation that he associated with the treasonous Fang Yi'ai (). Li Daozong died on the way to exile.
