Mao Dun (4 July 1896 – 27 March 1981) was the pen name of Shen Dehong (Shen Yanbing), a 20th-century Chinese novelist, cultural critic, and the Minister of Culture of People's Republic of China (1949–65). He is one of the most celebrated left-wing realist novelists of modern China. His most famous works are Ziye, a novel depicting life in cosmopolitan Shanghai, and Spring Silkworms. He also wrote many short stories.
He adopted "Mao Dun" (Chinese: 矛盾), meaning "contradiction", as his pen name to express the tension in the conflicting revolutionary ideology in China in the unstable 1920s. His friend Ye Shengtao changed the first character from 矛 to 茅, which literally means "thatch".
