Sharaf ad-DīnʿAlī Yazdī (Persian: شرف الدین علی یزدی‎) (born Yazd, Iran—died 1454, Yazd) was a 15th-century Persian[1] historian. Little about his early life is known. As a young man, he was a teacher in his native Yazd and a close companion of the Timurid ruler Shahrukh (1405–47) and his son Ibrahim Sultan.
