Wang Tingcou (王廷湊 or 王庭湊; died 834), formally the Duke of Taiyuan (太原公), was a general of the Chinese dynasty Tang Dynasty who, in 821, during the reign of Emperor Muzong, took over control of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) and thereafter ruled it in a de facto independent manner from the imperial government. He was said to be particularly cruel even for a warlord. After his death, his family held onto control of the circuit, even after the end of Tang Dynasty, until his great-great-grandson Wang Rong was overthrown in 921 – 100 years after Wang Tingcou had initially taken over the circuit.
