Empress Yan (閻皇后, personal name unknown) was an empress of the Chinese/Di (ethnic group) state Cheng Han. Her husband was Li Shou (Emperor Zhaowen). When Li Shou, after a coup, took over the throne from his cousin and the founding emperor Li Xiong's son Li Qi, he created her empress in 338. She bore him at least one son—the crown prince Li Shi, who succeeded Li Shou after Li Shou's death in 343. Li Shi honored her as empress dowager. Nothing else is recorded about her, and it is not known whether she survived to the destruction of the empire by Jin Dynasty (265-420) forces in 347.
