Tian Kai (died 199) was an official serving under the warlord Gongsun Zan during the late Eastern Han dynasty of China.
He probably started his career as a subordinate of the warlord Gongsun Zan in the Eastern Han dynasty.
In the second half of 191, when war broke out between Gongsun Zan and his rival Yuan Shao, Gongsun Zan sent Tian Kai to seize control of Qing Province, which was then under Yuan Shao's control.
Tao Qian, the Governor of Xu Province, approached his neighbours for help, one of whom was Tian Kai.
Tian Kai fought on Gongsun Zan's side in the Battle of Yijing and was killed in action.
