Wang Hongwen (December 1935 – August 3, 1992) was a Chinese labour activist and politician who spent most of his career in Shanghai.
He was an important political figure during the Cultural Revolution (1966–76).
He was the youngest member of the political clique called the "Gang of Four." During the Cultural Revolution, Wang rose from a member of the working class to become one of the foremost members of national leadership of the Communist Party of China.
At the pinnacle of his power he was the second Vice-Chairman of the CCP, and ranked third in the Communist Party's hierarchy.
Following Mao's death in 1976, Wang was arrested and charged with "counterrevolutionary activity," then sentenced to life imprisonment in 1981.
