In People's Republic of China (1949–), revolutionary operas or model operas (Simplified Chinese: yangban xi, 样板戏) were a series of shows planned and engineered during the Cultural Revolution (1966–1976) by Jiang Qing, the wife of Chairman Mao Zedong. They were considered revolutionary and modern in terms of thematic and musical features when compared with traditional Chinese operas. Many of them were adapted to film.

Originally, eight revolutionary operas (Chinese: Ba Ge Yangban Xi, 八个样板戏) were produced, eighteen by the end of the period. Instead of the "emperors, kings, generals, chancellors, maidens, and beauties" of the traditional Peking opera, which was banned as "feudalistic and bourgeois," they told stories from China's recent revolutionary struggles against foreign and class enemies. They glorified the People's Liberation Army and the bravery of the common people, and showed Mao Zedong and his thought as playing the central role in the victory of communism in China. Although they originated as operas, they soon appeared on LPs, in comic books (lianhuanhua), on posters, postcards, and stamps; on plates, teapots, wash basins, cigarette packages, vases, and calendars. They were performed or played from loudspeakers in schools, factories, and fields by special performing troupes. The Eight Model Operas dominated the stage in all parts of the country during these years, leading to the joke "Eight hundred million people watched eight shows."
