Li Jiji (李繼岌) (died May 28, 926), formally the Prince of Wei (魏王), nickname Hege (和哥), was an imperial prince of the Chinese Five Dynasties and Ten Kingdoms period state Later Tang. He was Later Tang's founder Emperor Zhuangzong of Later Tang (Li Cunxu)'s oldest son, and was commonly regarded at the time to be Emperor Zhuangzong's heir apparent. As such, he served as the titular commander of Later Tang's campaign to destroy its neighbor Former Shu, albeit with the major general Guo Chongtao in effective control. After Later Tang conquered Former Shu, however, under the command of his mother Empress Liu, Li Jiji killed Guo, leading to a chain reaction of mutinies that doomed Later Tang.
