Chairman Mao badge (Chinese: 毛主席像章; pinyin: Máo zhǔxí xiàngzhāng) is the name given to a type of pin badge displaying an image of Mao Zedong that was ubiquitous in the People's Republic of China during the active phase of the Cultural Revolution, from 1966 to 1971. The term is also used for badges associated with Mao that do not actually have a picture of him on them. It is estimated that several billion Chairman Mao badges were produced during the period of the Cultural Revolution.

Mao Zedong was a Chinese politician, Marxist theorist, military strategist, poet, and revolutionary who was the founder of the People's Republic of China. He led the country from its establishment in 1949 until his death in 1976, while also serving as the chairman of the Chinese Communist Party during that time.
