Wang Shichong (died 621), courtesy name Xingman, is a general of the Chinese Sui Dynasty who deposes Sui's last emperor Yang Tong and briefly rules as the emperor of a succeeding state of Zheng.

He first becomes 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 is able to defeat the rebel general Li Mi and seize Li Mi's territory.

After becoming emperor, however, he is unable to withstand military pressure from Tang Dynasty forces, forcing him to seek aid from Dou Jiande the Prince of Xia.

After Dou is defeated and captured by the Tang general Li Shimin (the later Emperor Taizong), Wang surrenders.

Emperor Gaozu of Tang spares him, but the Tang official Dugu Xiude, whose father Dugu Ji had been executed by Wang, assassinates him.
