Khosrow and Shirin () is the title of a famous tragic romance by the Persian poet Nizami Ganjavi (1141–1209), who also wrote Layla and Majnun. It tells a highly elaborated fictional version of the story of the love of the Sasanian king Khosrow II for the Armenian princess Shirin, who becomes queen of Persia. The essential narrative is a love story of Persian origin which was already well known from the great epico-historical poem the Shahnameh and other Persian writers and popular tales, and other works have the same title.
