Jiang Qin (168 – 219 A.D.), courtesy name Gongyi (公奕), was a military general for the Kingdom of Wu during the Three Kingdoms era of China. In the historical novel Romance of the Three Kingdoms by Luo Guanzhong, Jiang Qin was a pirate at the time he joined Sun Ce. He joined Sun Ce when Ce was taking over Liu Yao's territory in Jiangdong. Sun Ce trusted him greatly, and Jiang Qin was the holder of many titles, including "Army Guard of the Right". After Lü Meng's invasion of Jingzhou, Jiang Qin died of natural causes at the age of 51.
Once, Sun Quan walked into the inner halls of Jiang Qin’s house, and found that Jiang’s mother only had a light bed-curtain and cotton blankets, and his wives and concubines wore only simple cloth dresses. Sun Quan, greatly impressed by Jiang Qin’s virtue of living a frugal life despite his high rank, ordered his own household to make silken blankets for Jiang’s mother, and to exchange her curtains for better ones. His wives and concubines were given silken and embroidered clothes.
In an earlier time, Jiang Qin was on guard at Xuancheng, and was out fighting the bandits at Yuzhang. Xu Sheng, the prefect of Wuhu at that time, arrested an official of Jiang Qin’s, and requested Sun Quan for permission to behead him. As Jiang Qin was away, Sun Quan denied the request, but since then Xu Sheng estranged himself from Jiang Qin. Some time after that, Cao Cao lead an army out of Ruxu, and Jiang Qin and Lü Meng were made in charge of military discipline. Xu Sheng was constantly worried that Jiang Qin would find some reason to cause him harm. However, instead of that, Jiang Qin frequently gave high praises of Xu Sheng. At that, Xu Sheng became convinced of Jiang Qin’s virtues, and the men who discussed these things at that time considered well of Jiang Qin.
Jiang’s son, Yi, was made the Marquis of Xuancheng. He gained merits during the defence against Liu Bei, and returned to Nanjun where he fought with the Wei army. He died in battle there. Yi did not have offspring, and so his brother Xiu was given the military command, though he later was discharged due to misdemeanor.
