Emperor Ai of Tang (27 October 89226 March 908), also known as Emperor Zhaoxuan (), born Li Zuo, later known as Li Chu (), was the last emperor of the Tang dynasty of China. He reigned—as but a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong.

Li Yuan captured Chang'an in winter 617 and declared Emperor Yang's grandson Yang You emperor (as Emperor Gong), taking power himself as regent. After he received news in spring 618 that Emperor Yang had been killed at Jiangdu (江都, in modern Yangzhou, Jiangsu) in a coup led by the general Yuwen Huaji, he had Yang You yield the throne to him, establishing Tang Dynasty as its Emperor Gaozu. Li Shimin was created the Prince of Qin and thereafter became the main general in charge of his father's campaigns to reunify China under Tang rule, which was largely complete by 623, when the last major rival to Tang, Liu Heita the Prince of Handong, was captured and killed by Li Shimin's older brother, Li Jiancheng the Crown Prince. For Zhangsun Wuji's contributions to Li Shimin's campaigns, he was created the Duke of Shangdang.
