Han Ji 韓暨 (d. 238), courtesy name Gongzhi 公至, was a high official of the Wei dynasty 曹魏 (220-265) during the Three Kingdoms period 三國 (220-280).
He hailed from Duyang 堵陽 in the commandery of Nanyang 南陽 (today's Fangcheng 方城, Henan) and was recommended as a small official under the Minister of Works (sikong 司空), but he did not accept of post offer. Han also declined offers for employment by the warlords Yuan Shu 袁術 and Liu Biao 劉表. Yet fearing the latter's anger, he finally accepted a post as mayor of Yicheng 宜城.
When Cao Cao 曹操 conquered central China, he was made clerk in the agricultural section of the Counsellor-in-chief (chengxiang tucao 丞相土曹), later governor (taishou 太守) of the commandery of Leling 樂陵, and supervisor of the ironworks (jianye yezhe 監冶謁者). During that time the bellows were driven by the power of horses or men. Han suggested to use the force of water, with excellent results. He was rewarded with the post of sijin duwei XXX.
Emperor Wen 魏文帝 (r. 220-226) granted him the title of Neighbourhood Marquis of Yicheng 宜城亭侯. Han Ji was appointed Chamberlain for Ceremonials (taichang 太常) and rose to the status of Neighbourhood Marquis of Nanxiang 南鄉亭侯. In 238, more than eighty years old, he was given the title of Minister of Education (situ 司徒), but died shortly thereafter. His posthumous title was Marquis Gong 南鄉恭侯.
