Abdallah ibn Tahir (Persian: عبدالله طاهر, Arabic: عبد الله بن طاهر الخراساني) (ca. 798–844/5) was a military leader and the Tahirid governor of Khurasan from 828 until his death. He is perhaps the most famous of the Tahirids. His career spanned twenty-five years under three caliphs, al-Ma'mun, al-Mu'tasim, and al-Wathiq. Militarily, he is known for defeating the powerful rebels Nasr ibn Shabath in the Jazira (Upper Mesopotamia) and Ubaydallah ibn al-Sari in Egypt.
