Yan Jun ( 200s–240s), courtesy name Mancai, was an official of the state of Eastern Wu during the Three Kingdoms period of China. Life Yan Jun was from Pengcheng (), which is present-day Xuzhou, Jiangsu. He was known for being very studious since he was young and was well versed in Confucian classics.
