Wang Jun (王峻) (c. 902 – 953) was one of the first chancellors of imperial China's short-lived Later Zhou during the Five Dynasties and Ten Kingdoms period. He started his career as a singer for those in power, and rose to high prominence due to his association first with military general Liu Zhiyuan, founder of the Later Han, and later Guo Wei, who founded Later Zhou. After becoming the Later Zhou chancellor, his excessive actions gradually created a lot of distrust in Guo, culminating in his precipitous political downfall right before his death.
