Mu Dan (Chinese: 穆旦) (5 April 1918 - 26 February 1977) is a prominent 20th Century Chinese poet and translator. He obtained degrees in both China and the USA and joined the Chinese Expedition force to fight the Japanese in Burma for a time.

Most of his work was completed in the 1930s and 1940s and was heavily influenced by English romantic poets such as W.B Yeats and T.S.Eliot. His work is of the foremost examples of Chinese venacular poetry, although his work often has unmistakeable traces of patriotism that are firmly in line with Chinese tradition.After the establishment of the People's Republic of China in 1949, Mu Dan was forced to stop writing poetry and turned to translation.
