Wang Shoucheng (王守澄) (died November 3, 835) was a powerful eunuch of the Tang dynasty of China, wielding substantial powers during the reigns of Emperor Xianzong, Emperor Muzong, Emperor Jingzong, and Emperor Wenzong. By 835, however, two non-eunuchs that he had recommended to Emperor Wenzong — Li Xun and Zheng Zhu — were plotting with Emperor Wenzong to exterminate the eunuchs, and as part of the plan, Emperor Wenzong sent poison to Wang and ordered him to commit suicide.
