Du Mu (Chinese: 杜牧; pinyin: Dù Mù; Wade–Giles: Tu4 Mu4; 803–852) was a Chinese calligrapher, poet, and politician who lived during the late Tang dynasty. His courtesy name was Muzhi (牧之), and art name Fanchuan (樊川). He is best known for his lyrical and romantic quatrains.

Tang poetry refers to poetry written in or around the time of or in the characteristic style of China's Tang dynasty, and/or follows a certain style, often considered as the Golden Age of Chinese poetry. The Complete Tang Poems includes over 48,900 poems written by over 2,200 authors. During the Tang dynasty, poetry continued to be an important part of social life at all levels of society. Scholars were required to master poetry for the civil service exams, but the art was theoretically available to everyone. This led to a large record of poetry and poets, a partial record of which survives today. The two most famous poets of the period were Li Bai and Du Fu. The Qing dynasty selection, Three Hundred Tang Poems, has made Tang poetry familiar to educated Chinese in modern times.
