Empress Guo (fl.220 – 8 February 264[1]), personal name unknown, formally known as Empress Mingyuan, was an empress of the state of Cao Wei during the Three Kingdoms period of China. She was married to Cao Rui, the second ruler of Wei; she was his third wife and second empress. The limited information available about her appears to portray her as an intelligent woman who fought hard to prevent her empire from falling into the hands of the Sima clan (Sima Yi and his sons Sima Shi and Sima Zhao) during the reigns of her adopted son Cao Fang and his cousin Cao Mao, but was unable to stem the tide.
