Jin is a state of the Chinese Five Dynasties and Ten Kingdoms period.

Its rulers Li Keyong and Li Keyong's son Li Cunxu, of Shatuo extraction, claim to be rightful subjects of the defunct Tang Dynasty in a struggle against the usurper state Later Liang Dynasty.

At the time of Tang's fall in 907, the Jin state constitutes most, but not all, of modern Shanxi, and eventually expands to cover all of the territory north of the Yellow River.

Eventually, in 923, Li Cunxu, claiming rightful succession to the Tang throne, declares himself emperor, transitioning his state to the Later Tang Dynasty, which shortly after destroys Later Liang.
