Sun Ce's conquests in Jiangdong were a series of military campaigns by the warlord Sun Ce to conquer territories in the Jiangdong and Wu regions from 194 to 199 towards the end of the Eastern Han dynasty. The conquered lands served as a foundation for the state of Eastern Wu during the Three Kingdoms period (220–280). Background Sun Ce was the eldest son of the warlord Sun Jian, who was killed in action during the Battle of Xiangyang in 191 against Liu Biao, the Governor of Jing Province.

Yuan Shu then sent Sun Ce to attack Lu Kang and told him before he left, "It was my mistake to appoint Chen Ji, and now I often regret not abiding by my original decision. If you defeat Lu Kang, Lujiang will truly be yours." However, Yuan Shu broke his promise again after Sun Ce conquered Lujiang Commandery as he appointed Liu Xun as the Administrator instead.
