Shi Yuanzhong (Chinese: 史元忠; died October 14, 841[1][2]) was a Chinese general of the Tang dynasty, serving for several years as the military governor (Jiedushi) of Lulong Circuit (盧龍, headquartered in modern Beijing) and ruling it in de facto independence from the imperial government until he was killed in 841.
As of 834, he was serving as a battlefield commander (兵馬使, Bingmashi) at Lulong, when the soldiers mutinied and expelled the military governor Yang Zhicheng and the eunuch monitor of the army Li Huaiwu (李懷仵).
Then-reigning Emperor Wuzong (Emperor Wenzong's younger brother), under the advice of the chancellor Li Deyu, declined to take immediate action on petitions submitted on Chen's behalf for Chen to become military governor.
Soon thereafter, Chen himself was assassinated, and the soldiers supported another officer, Zhang Jiang (張絳) to be their leader.
Thereafter, when Lulong officer Zhang Zhongwu, who was then the commander of Xiongwu Base (雄武軍, in modern Chengde, Hebei), requested imperial commission and permission to attack Zhang Jiang, Emperor Wuzong, again under Li Deyu's advice, agreed, and Zhang Zhongwu soon captured Lulong's capital You Prefecture (幽州) and took over the circuit.
