Han Kuangsi (simplified Chinese: 韩匡嗣; traditional Chinese: 韓匡嗣; pinyin: Hán Kuāngsì; 918–983) was a physician and minister of the Liao dynasty. He wrote The Epitaph of Han Kuangsi (韩匡嗣墓志), which was discovered in the Bairin Left Banner in 1995.

Han Kuangsi served in Changle Palace (长乐宫). Empress Shulü Ping regarded him as her son. However he did not occupy a high position under Emperor Taizong and Emperor Muzong. Han later went to Emperor Taizu's memorial temple where he was examined and secured. Han also befriended Yelü Xian and later helped him to ascend to the throne as Emperor Jingzong. After this, Han was appointed as the Jiedu Envoy of the Shiping Army (始平军节度使). He also served him in Beijing and stayed in Nanjing as a Southwest secret envoy, also handling the Jinchang Army Jiedu Envoy (晋昌军节度使等). Because of this contribution, Han Kuangsi was honoured as King of Fengyan (封燕王) and later King of Qin (秦王).

In October, along with Yelü Xiuge and Yelü Sha, Han led 50,000 horses to attack Zhenzhou and Song dynasty's soldiers in Mancheng. However, Han made a wrong command and then his army was defeated; Yelü Xiuge also retreated from the enemy. Hearing this, the Emperor Jingzong ordered Han Jusi (韩巨嗣) to change him, and awarded Xiuge the title Great King of the Northern (为北院大王).
