Wei Guan (simplified: 卫瓘, traditional: 衛瓘, pinyin: Wèi Guàn), courtesy name Boyu (伯玉), was a general and minister who served Sima Zhao during the Wei conquest of Shu. He was sent to supervise Zhong Hui and Deng Ai. After Shu surrendered, Zhong Hui falsely accused Deng Ai of rebellion; Wei Guan arrested Deng Ai. When Zhong Hui then rebelled with Jiang Wei, Wei Guan rallied loyal troops; Zhong Hui and Jiang Wei were killed in the ensuing chaos. Wei Guan had Deng Ai killed on the road (fearing reversal of the verdict). He later served Sima Yan under the Jin dynasty and was killed in 291 by the faction of Empress Jia.
