Fazlallah Khunji Isfahani (Persian: فضل الله خنجی اصفهانی; 1455–1521), was a Persian religious scholar, historian and political writer.
He was born in 1455 in Shiraz, a city in Fars, a region in southern Iran.
His father belonged to the Ruzbihan family, which was descended from the Sufi author Ruzbihan Baqli (died 1209), while his mother belonged to the Sa'idi family.
Through both his parents, Khunji belonged to the affluent and influential ulama (clergical class) of Fars, who were respected and protected by the Turkmen Aq Qoyunlu.
When the Safavid shah Ismail I started the Shi'ification of Iran and the persecution of Sunni Muslims, Khunji fled to Transoxiana, where he lived for the rest of his life under the patronage of Timurids and Shaybanids.
