Overview
Wang Jingchong (; 847–883), courtesy name Meng'an, formally Prince Zhongmu of Changshan, was a general of the Chinese Tang Dynasty who followed a line of his ancestors in ruling Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) as its military governor (Jiedushi) in de facto independence from the imperial government.

Emperor Xuānzong approved the succession.
