Li Cunjin (李存進) (855 – 24 September 922), originally Sun Chongjin (孫重進), was a military general in imperial China's Tang Dynasty, and later the Jin territory in the ensuing Five Dynasties and Ten Kingdoms period after Tang's collapse. He served the Shatuo leaders Li Keyong — who adopted him as a son — and Li Keyong's biological son and successor Li Cunxu. He died in the battles against Zhang Chujin.
