Du Zeng (died 319) was a Chinese military general and rebel of the Jin dynasty (266–420). In 312, he joined his fellow general, Hu Kang (胡亢), in rebelling against Jin from Jingling Commandery (竟陵, roughly modern Jingmen, Hubei), but later killed him and assumed leadership of the rebellion. Du Zeng, along with another rebel leader, Du Tao, became a persistent threat to Jin in the south as he caused trouble in Jingzhou and Xiangzhou (湘州; in modern Hunan). Eventually, he was decisively defeated by the general, Zhou Fang in 317, before being captured and executed in 319. As subordinate of Sima Xin and Hu Kang Du Zeng was from Xinye County in Nanyang Commandary and started his career under the Prince of Xinye, Sima Xin (司馬歆). Du Zeng was said to be a very strong man, being able to swim across a river while wearing armor. Under Sima Xin, he rose to the rank of Colonel of the Southern Man Tribes and was present wherever Sima Xin went up to his death at the hands of Zhang Chang in 303. In 312, in light of the Disaster of Yongjia, Hu Kang, another general of Sima Xin, took the opportunity to gather men at Jingling Commandery and start a rebellion, declaring himself Duke of Chu. Du Zeng joined Hu Kang and became his provisional Administrator of Jingling. However, Hu Kang proved to be a problematic leader due to his paranoia that made him execute many of his generals. Du Zeng plotted to get rid of him, but feigned loyalty at first to gain his trust. Later that year, Du Zeng supported Hu Kang's decision to campaign against the bandit Wang Chong (王沖). Du Zeng had artisans to tamper with Hu Kang's personal guards' weapons before secretly enticing Wang Chong to attack. Hu Kang sent out all his men against Wang Chong, leaving himself defenceless within the city. Du Zeng assassinated him and declared himself General of the Household Gentlemen and acting Administrator of Jingling. Leading the rebellion Du Zeng's first objective was to enter an alliance with the Administrator of Nan Commandary, Liu Wu (劉務). After Liu Wu refused to marry Du Zeng's daughter, Du Zeng had him killed. Later, the Jin general Tao Kan's subordinate, Wang Gong (王貢) forged an order seemingly from his superior appointing Du Zeng as Grand Commander of the Vanguard. Wang Gong then killed Wang Chong
