Qutb al-Din Shirazi (1236 – 1311) was a Persian polymath, Sufi, and poet.

Biography
Qutb al-Din was born on October 1236 in the city of Shiraz, which at the time served as the capital of the Salghurid atabegate. He belonged to the Kazaruni family, which was distinguished for its physicians. His father Zia al-Din Mas'ud Kazaruni, was a renowned physician and Sufi who worked at the Muzaffari hospital in Shiraz. Under his guidance, Qutb al-Din studied medicine. He also studied the Qanun (the Canon) by the scholar Avicenna (died 1037), as well as its commentaries, especially the one by Fakhr al-Din Razi (died 1210), which he considered to have many errors. Following Zia al-Din's death, Qutb al-Din, at the age of fourteen, succeeded him as an ophthalmologist at the Muzaffari hospital. He also continued his studies in medicine, this time under Kamal al-Din Abu'l-Khayr, and then later under Sharaf al-Din Zaki Bushkani and Shams al-Din Muhammad Kishi, both well-versed in the Qanun.

Qutb al-Din later went to Tabriz, where he stayed during his final years. He died on 7 February 1311 and was buried in the Charandab Cemetery of the city, near the tomb of Qadi Baydawi (died 1319).
