Li Jiao (Chinese: 李嶠), courtesy name Jushan (巨山), formally the Duke of Zhao (趙公), was an official of the Chinese Tang Dynasty and Wu Zetian's Zhou Dynasty, serving as chancellor during the reigns of Wu Zetian, her sons Emperor Zhongzong and Emperor Ruizong, and her grandson Emperor Shang.
It is not known exactly when Li Jiao was born, but it is known that his family was from Zhao Prefecture (趙州, roughly modern Shijiazhuang, Hebei). He came from a prominent clan, and his great-granduncle Li Yuancao (李元操) was a well-known official during Tang Dynasty's predecessor Sui Dynasty. His father Li Zhen'e (李鎮惡), who had served as the magistrate of Xiangcheng County (襄城, in modern Xuchang, Henan), died early, and it was said that Li Jiao served his mother Lady Zhang with great filial piety. His literary talent began to be known when he was young, and his reputation matched that of Su Weidao, who was also from Zhao Prefecture. He already understood the Five Classics at age 14 and was praised by the chancellor Xue Yuanchao. He passed the imperial examination at age 19 and was made the sheriff of Anding County (安定, in modern Dingxi, Gansu). He was soon promoted to serve in the capital Chang'an, and he, along with older colleagues Luo Binwang and Liu Guangye (劉光業), became known for their literary talent.
