Ahmad Shāmlou (Persian: احمد شاملو) (December 12, 1925 — July 24, 2000) was a Persian poet, writer, and journalist. His poetry was initially very much influenced by and was in the tradition of Nima Youshij. Shamlou's poetry is complex, yet his imagery, which contributes significantly to the intensity of his poems, is simple. As the base, he uses the traditional imagery familiar to his Iranian audience through the works of Persian masters like Hafez and Omar Khayyám. For infrastructure and impact, he uses a kind of everyday imagery in which personified oxymoronic elements are spiked with an unreal combination of the abstract and the concrete thus far unprecedented in Persian poetry, which distressed some of the admirers of more traditional poetry.

Shamlou has translated extensively from German and French to Persian and his own works are also translated into a number of languages. He has also written a number of plays, edited the works of major classical Persian poets, especially Hafez. His six-volume Ketab-e Koucheh (The Book of the streets) is a major contribution in understanding the Iranian folklore beliefs and language. Aside from his first passion which was poetry, he had a number of other activities which included writing stories and film scenarios, contributing to children’s literature, and journalism.
