Khwāja Shams-ud-Dīn Muḥammad Ḥāfeẓ-e Shīrāzī, known by his pen name Hafez(حافظ Ḥāfeẓ; 1325/26–1389/90), was a Persian poet who "laud[ed] the joys of love and wine [but] also targeted religious hypocrisy". His collected works are regarded as a pinnacle of Persian literature and are to be found in the homes of most people in Iran, who learn his poems by heart and use them as proverbs and sayings to this day. His life and poems have been the subject of much analysis, commentary and interpretation, influencing post-14th century Persian writing more than any other author.

Themes of his ghazals are the beloved, faith, and exposing hypocrisy. His influence in the lives of Persian speakers can be found in "Hafez readings" (fāl-e hāfez, Persian: فال حافظ‎‎) and the frequent use of his poems in Persian traditional music, visual art, and Persian calligraphy. His tomb is visited often. Adaptations, imitations and translations of Hafez' poems exist in all major languages.
