Wang Shichong, courtesy name Xingman (行滿), was a Chinese military general, monarch, and politician during the Sui dynasty who deposed Sui's last emperor Yang Tong and briefly ruled as the emperor of a succeeding state of Zheng. He first became prominent during the reign of Emperor Yang of Sui as one of the few Sui generals having success against rebel generals, and during Yang Tong's brief reign, he was able to defeat the rebel general Li Mi and seize Li Mi's territory. After becoming emperor, however, he was unable to withstand military pressure from Tang dynasty forces, forcing him to seek aid from Dou Jiande the Prince of Xia. After Dou was defeated and captured by the Tang general Li Shimin, Wang surrendered. Emperor Gaozu of Tang spared him, but the Tang official Dugu Xiude (獨孤修德), whose father Dugu Ji (獨孤機) had been executed by Wang, assassinated him.

Emperor Yang of Sui, personal name Yang Guang (楊廣), alternative name Ying (英), Xianbei name Amo (阿摩), also known as Emperor Ming of Sui (隋明帝) during the brief reign of his grandson Yang Tong, was the second emperor of the Sui dynasty of China.
