Li Shiji (李世勣) (594 – December 31, 669), né Xu Shiji (徐世勣), later known in the reign of Emperor Gaozong of Tang as Li Ji (李勣), courtesy name Maogong (懋功), formally Duke Zhenwu of Ying (英貞武公), was one of the most celebrated generals early in the Chinese Tang Dynasty. He was initially a follower of Li Mi, one of the rebel rulers rebelling against the preceding Sui Dynasty, and he submitted to Tang after Li Mi did so, upon which Emperor Gaozu, impressed with his loyalty to Li Mi, bestowed on him the imperial clan name of Li. He later participated in destroying Xu Yuanlang and Fu Gongshi, two of Tang's competitors on Tang's campaign to reunify China. During the reign of Emperor Gaozu's son Emperor Taizong, he participated in the successful campaigns destroying Eastern Tujue and Xueyantuo, allowing Tang to become the dominant power in eastern Asia, and also served as a chancellor. During the reign of Emperor Gaozong, he served as chancellor and the commander of the army against Goguryeo, destroying Goguryeo in 668. He died the next year. He and Li Jing were considered the two most prominent early Tang generals.
