Liu Ji (184–233), courtesy name Jingyu, was a Chinese politician of the state of Eastern Wu in the Three Kingdoms period of China.
He was a descendant of the imperial clan of the Han dynasty and the eldest son of the minor warlord Liu Yao.
In 219,[8] when Sun Quan was appointed General of Agile Cavalry (驃騎將軍) by the Han imperial court, he recruited Liu Ji to serve as an Assistant in the East Bureau (東曹掾) and subsequently promoted him to Colonel Who Upholds Righteousness (輔義校尉) and Palace Gentleman Who Builds Loyalty (建忠中郎).
[9] In 221,[10] after Sun Quan received the nominal vassal title "King of Wu" (吳王) from the Wei emperor Cao Pi, he appointed Liu Ji as Grand Prefect of Agriculture (大農令).
He told Sun Quan, "If Your Majesty kills a good man when you're drunk, even if Yu Fan is in the wrong, who would understand the truth?
Sun Quan said, "If Cao Mengde can kill Kong Wenju, why can't I do the same to Yu Fan?"
[11][12] On one hot summer day, when Sun Quan was feasting on board a ship, a thunderstorm suddenly broke out.
[13] In 229, after Sun Quan declared himself emperor and established the state of Eastern Wu,[14] he appointed Liu Ji as Minister of the Household (光祿勳; or Superintendent of the Imperial Court), in addition to giving him some duties of a Master of Writing (尚書).
