Ruan Ji (210–263), courtesy name Sizong, was a Chinese musician, poet, and military officer who lived in the late Eastern Han dynasty and Three Kingdoms period. He was one of the Seven Sages of the Bamboo Grove. The guqin melody Jiukuang (酒狂 'Drunken ecstasy', or 'Wine-mad') is believed to have been composed by him. At one time an infantry colonel, he was also known as Ruan Bubing (阮步兵; 'Ruan of the infantry').
