Empress Li (李皇后, personal name unknown) was an empress of the Chinese/Di state Cheng Han. Her husband was Li Shi, the last emperor of Cheng Han. She was his wife when he was crown prince under his father Li Shou, and when he succeeded his father in 343, he created her empress. Nothing further is known about her, including whether she survived to or survived Cheng Han's destruction by Jin Dynasty (265-420) forces in 347. If she did, since her husband was created the Marquess of Guiyi, she would have carried the title of marchioness.
