Zhang Hongjing (simplified Chinese: 张弘靖; traditional Chinese: 張弘靖; pinyin: Zhāng Hóngjìng) (760 – July 24, 824[1][2]), courtesy name Yuanli (元理), formally the Marquess of Gaoping (高平侯), was an official of the Tang dynasty of China, serving as a chancellor during the reign of Emperor Xianzong. He was blamed in traditional histories for misruling Lulong Circuit (盧龍, headquartered in modern Beijing), leading to Lulong soldiers' subsequent rebellion against the imperial government under Zhu Kerong.
