Li Daoguang (李道廣), courtesy name Taiqiu (太丘),[1] formally Marquess Cheng of Jincheng (金城成侯), was an official of Wu Zetian's Zhou dynasty, serving as chancellor for about two years.
His family was originally from what would become Hua Prefecture (滑州, roughly modern Anyang, Henan), but by Li Daoguang's time had moved to the Tang dynasty capital Chang'an.
Li Daoguang's great-grandfather Bing Ming (丙明) served as a commandant during Sui dynasty and was created the Duke of Longju.
During the reign of Emperor Gaozong's wife Wu Zetian (r. 690–705), Li Daoguang served as the prefect of Bian Prefecture (汴州, roughly modern Kaifeng, Henan).
Later that year, he was recalled serving as director of palace affairs (殿中監, Dianzhong Jian), and Wu Zetian gave him the designation Tong Fengge Luantai Pingzhangshi (同鳳閣鸞臺平章事), making him a chancellor de facto.
