Liu Wuzhou (died 622?)

is a rebel leader who rises against the rule of the Chinese dynasty Sui Dynasty late in the dynasty's history, and he takes imperial style -- although it was not completely clear whether the title he took was khan or tianzi.

He is initially only able to take control of modern northern Shanxi and parts of central Inner Mongolia, but after Li Yuan establishes the Tang Dynasty at Chang'an as its Emperor Gaozu in 618, he, with support from Eastern Tujue, briefly captures Li Yuan's initial power base of Taiyuan in 619, posing a major threat to Li Yuan's rule.

In 620, Li Yuan's son Li Shimin (the future Emperor Taizong) counterattacks, and not only recaptures Taiyuan but further captures Liu's power base Mayi (in modern Shuozhou, Shanxi), forcing Liu to flee to Eastern Tujue.

When Liu subsequently tries to flee back to Mayi, the Eastern Tujue Khaganate executes him.
