Xu Zhimo (Chinese: 徐志摩; pinyin: Xú Zhìmó; January 15, 1897—November 19, 1931) was an early 20th century Chinese poet. He was given the name of Zhangxu (章垿) and the courtesy name of Yousen (槱森). He later changed his courtesy name to Zhimo (志摩).

He is romanticized as pursuing love, freedom, and beauty all his life (from the words of Hu Shi). He promoted the form of modern Chinese poetry, and therefore made tremendous contributions to modern Chinese literature.

To commemorate Xu Zhimo, in July, 2008, a white marble stone has been installed at the back of King's College, University of Cambridge, on which is inscribed a verse from Xu's best-known poem, 'Saying Goodbye to Cambridge Again'.
