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. He shared the same personal name as Sima Zhao (司馬昭,an ancestor of the Jin dynasty emperors) so, 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).
