Tian Yu (c.171 –c.252),courtesy nameGuorang, was a military general of the state ofCao Wei during theThree Kingdoms period of China.

Tian Yu was from Yongnu County (雍奴縣),Yuyang Commandery (漁陽郡), which is present-dayWuqing District,Tianjin.^[3] DuringLiu Bei's stay withGongsun Zan, the young Tian Yu placed himself under Liu Bei's foster care, and Liu Bei was greatly impressed by Tian Yu.^[4] When Liu Bei was Inspector of Yu Province, Tian Yu left to care for his ageing mother; Liu Bei tearfully expressed his regret at not being able to work with Tian Yu.^[5]

Later Tian Yu served under Gongsun Zan as the Prefect of Dongzhou County (東州縣). One of Gongsun Zan's generals, Wang Men (王門), betrayed Gongsun Zan and joined Yuan Shao, and lead an attack on his former master with more than 10,000 troops.^[6] Tian Yu personally visited Wang Men and managed to shame the latter into retreating.^[7] Although Gongsun Zan knew of Tian Yu's intellect, he could not appoint important roles for Tian Yu.^[8] After Gongsun Zan's defeat, Tian Yu's friend Xianyu Fu hired him as an adjutant.^[9] He recommended that Xianyu Fu joinCao Cao,^[10] who subsequently hired Tian Yu as well in various official positions.^[11]

After Cao Cao's sonCao Pi deposedEmperor Xian of Han in November 220 and crowned himself emperor in December that year, Tian Yu continued to serveCao Wei.

Tian Yu was appointed Colonel Who Protects the Wuhuan early in Cao Pi's reign and he served in the position for about nine years with distinction. However, cronies of the Inspector ofYou Prefecture Wang Xiong (王雄; grandfather ofWang Rong andWang Yan) wanted Wang to have the position. Thus, they slandered Tian Yu as causing disruption at the border and creating trouble for the state. Tian Yu was then appointed Administrator of Ru'nan and General Who Eliminates the Yi.^[12]

Towards the end of theJingchu era (237 - 239), Tian Yu's fiefdom was increased by 300 households, to a total of 500 households.^[13]

In the early part of theZhengshi era (240-249) of Cao Fang's reign, Tian Yu was made General of the Household Who Protects theXiongnu, General Who Inspires Might and Inspector ofBing Province. During his tenure, foreign minorities were in awe of him and one by one, they brought tribute. The border regions became peaceful and quiet, and this was cherished by the residents. Later, he was also appointed Minister of the Guards. By then in his 70s, Tian Yu frequently requested to resign his positions; the Grand TutorSima Yi thought that Tian was still fit enough to carry out his duties and so rejected his requests. As a reply, Tian Yu wrote, "To be occupying positions above the age of 70 is like continuing to travel at night even after bells had been rung and thewater clocks had run out; it is a crime." Tian then insisted that he was gravelly ill. As such, he was appointed Palace Counsellor, and continued to draw a salary.

Tian Yu died at the age of 82 (by East Asian reckoning) in the 240s or early 250s, and his peerage was inherited by his son Tian Pengzu.^[14]
