Chen Tai (died c.June 260[3]),[2] courtesy name Xuanbo, was a military general and official of the state of Cao Wei during the Three Kingdoms period of China.
When he was recalled back to the imperial capital Luoyang in 249, Sima Yi had just seized power in a coup against his co-regent, Cao Shuang.
Cao Shuang did so and was executed along with most of his clan/inner circle later as part of Sima Yi's plan to gain complete control over the Wei government.
Chen Tai initially favoured the changes in the political environment as he believed that Sima Yi was far more capable as a regent than Cao Shuang.
To avoid getting caught up in the political rivalries, he requested to be transferred to the western border to guard against invasions by Wei's rival state, Shu Han.
Guo Huai, along with Chen Tai and Deng Ai, led the Wei forces to besiege the Shu camp at Mount Chu.
Chen Tai ordered Wang Jing, the Inspector of Yong Province, to defend Didao and guard the fortress while waiting for reinforcements.
Wei forces led by Deng Ai, Wang Bi and Hu Fen came to join Chen Tai's army.
In Luoyang, Chen Tai first served as the Right Supervisor of the Masters of Writing (i.e. the Imperial Secretariat) under the administration of the regent Sima Zhao.
Upon seeing Cao Mao's dead body, he wept and refused to attend imperial court sessions as a protest against the emperor's assassination.
