Wang Hongwen (December 1935 – 3 August 1992; also spelled as Wang Hung-wen) was a Chinese politician who was the youngest member of the Gang of Four. He rose to prominence during the Cultural Revolution (1966–1976), after organizing the Shanghai People's Commune, to become one of the foremost members of national leadership of the Chinese Communist Party (CCP).
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 deposed in an intra-party coup, arrested and charged with "counterrevolutionary activity", then sentenced to life imprisonment in 1981.
