Şahkulu (Ottoman Turkish: شاه قولی; Persian: شاهقلی بغدادی Shāhqulī-i Baghdādī; died 1556) was an Ottoman painter who played a leading role in a formation of the saz style.
Saz style "in which mythical creatures derived from Chinese or Islamic sources move through an enchanted forest made up of oversized composite blossoms and feathery leaves, has parallels in the art of the Aqqoyunlu and Safavid courts at Tabriz, where Shahquli trained under a master named Aqa Mirak" (it was not the well-known painter of Tahmasp's court). According to Sam Mirza Safavi (who does not mention his emigration to Ottoman lands) Şahkulu came from Qom. His name is in a document found in Ottoman Archives among the scholars and artisans who were exiled from Tabriz to Istanbul via Amasya on 12 April 1515, the aftermath of Ottoman occupation of Tabriz after the battle of Chaldiran. The 1525-26 register of court artisans list him as the head draftsman (ressam) of the twenty-nine artists and twelve apprentices employed there, with high daily salary of twenty two akçe. He became popular with Suleiman, to whom he gave a picture of a peri, and received gifts including 2000 akçe and broaded caftans and velvets. Another register from the same year adds the note that he joined the Istanbul naqqash khana ("painter's house") in 1520–21.
