Xu Hun (traditional Chinese: 許渾; simplified Chinese: 许浑; pinyin: Xǔ Hún; Wade–Giles: Hsü Hun, fl.
first half of ninth century) was a Chinese poet.
By passing the rigorous requirements of the imperial examination system, he received his Jinshi degree, in 832, and subsequently followed a "moderately distinguished" professional scholarly career.
Two of Xu Hun's verses are included in the famous poetry anthology Three Hundred Tang Poems, both in the five-character regulated verse form.
His work has been compared in style with Li Shangyin and Wen Tingyun.
