Zhang Yunshen (Chinese: 張允伸) (785[1] – March 8, 872[2][3]), courtesy name Fengchang (逢昌), formally Duke Zhonglie of Yan (燕忠烈公), was a general of the Chinese Tang dynasty who ruled Lulong Circuit (盧龍), headquartered in modern Beijing in de facto independence from the imperial government.
In 869, when the imperial government was facing a major rebellion led by Pang Xun at Xu Prefecture (徐州, in modern Xuzhou, Jiangsu), Zhang offered to have his brother Zhang Yungao (張允皐) command an army to assist the imperial operations.
[1] In 870, Emperor Yizong further bestowed the greater honorific chancellor title of Shizhong (侍中) on Zhang.
[3] In 872, Zhang suffered a stroke, and he submitted a petition to yield his responsibilities so that he could attend to his medical condition.
Emperor Yizong agreed and made his son Zhang Jianhui the acting military governor.
