Wang Chong (27 AD - about 97 AD), courtesy name Zhongren, was a Han nationality and a native of Shangyu, Kuaiji (now Shangyu, Shaoxing, Zhejiang). Thinker of the Eastern Han Dynasty. He was an important inheritor and developer of Taoist thought in the Han Dynasty.

Although his thoughts belong to Taoism, they are strictly different from the thoughts of Lao and Zhuang in the pre-Qin Dynasty. Although he is the advocate of Taoism in the Han Dynasty, it is different from the "School of Huang and Lao" advertised by the early Han Dynasty and the Western Han Dynasty. The popular Taoism among the people in the late period was different. "Lunheng" is Wang Chong's representative work and an immortal ideological work in Chinese history.
