Wei Zhao (204–273), courtesy name Hongsi, was an official, historian, and scholar of the state of Eastern Wu during the Three Kingdoms period of China.
In order to avoid naming taboo, the historian Chen Shou changed Wei Zhao's personal name to "Yao (矅)" when he wrote Wei Zhao's biography in the Sanguozhi (the authoritative source for the history of the Three Kingdoms period).
Wei Zhao was appointed as the first Erudite Libationer (博士祭酒; i.e. President) of the precursor to the Imperial Nanking University by the third Wu emperor, Sun Xiu, in 258.
Wei Zhao's insistence on producing a historically accurate Book of Wu resulted in his execution by Sun Hao.
Wei Zhao also wrote several other works, such as Annotations to Guoyu (國語注) and Argument and Interpretation of Names (辯釋名).
