Li Jing (??, pinyin: L? Jìng) (571 – July 2, 649), born Yaoshi (??/??, pinyin: Yàosh?), formally Duke Jingwu of Wei (????), was a general and one time chancellor of the Chinese Tang Dynasty. In 630, Li Jing defeated the Eastern Tujue (Göktürk) Jiali Khan Ashina Duobi with just 3,000 cavalry soldiers in a surprise attack, allowing Tang to subjugate Eastern Tujue and reduce it to a vassal state. He and Li Shiji were considered the two most prominent early Tang generals.
