Empress Li (李皇后, personal name unknown) (d. October 7, 950) was a princess of the Chinese Five Dynasties and Ten Kingdoms Period state Later Tang (as a daughter of its emperor Li Siyuan) and an empress of the succeeding Later Jin (as the wife of its founding emperor Shi Jingtang).
It is not known when the future Empress Li was born. It is known that she was Li Siyuan's third daughter. Her mother was Li Siyuan's wife Lady Cao, who would later be empress during Li Siyuan's reign. It is not known exactly when she married Shi Jingtang, but as of 919, at which time her father Li Siyuan was still a general of Later Tang's predecessor state Jin and Shi was an officer under him, Shi was already referred to as a son-in-law of his, suggesting that they were married by that point. In 928, by which time Li Siyuan was emperor of Later Tang, he created Lady Li the Princess Yonging. In 933 (just before Li Siyuan's death), he created her the Princess of Wei. She and Shi Jingtang had at least one son, Shi Chongxin (石重信); it is not known whether any of his other five known sons or any daughter of his was born of her.
In 934, the Princess's biological half-brother Li Conghou, then emperor, was facing the rebellion by their adoptive brother (Li Siyuan's adoptive son) Li Congke the Prince of Lu, who was advancing toward the capital Luoyang from his post as military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi). Shi, initially intending to support Li Conghou, launched his own troops from Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) toward Luoyang. By the time he reached Luoyang's vicinity, however, Li Congke's army had already entered Luoyang, and Li Conghou had fled. Instead of supporting Li Conghou when he encountered Li Conghou, Shi slaughtered Li Conghou's guards, leaving him completely vulnerable. Li Congke subsequently had Li Conghou killed and took the throne.
