Wang Yuankui (Chinese: 王元逵; 812–854), formally Duke Zhong of Taiyuan (太原忠公), was a general of the Chinese dynasty Tang Dynasty. Like his father Wang Tingcou, Wang Yuankui ruled Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) in de facto independence from the imperial government, but unlike Wang Tingcou, he was respectful to the imperial government and often followed its orders.
