Ṭāhir ibn Ḥusayn (Persian: طاهر بن حسین‎‎, Arabic: طاهر بن الحسين‎‎), also known as Dhul-Yamīnayn (Arabic: ذو اليمينين‎‎, "the ambidextrous"), and al-Aʿwar (Arabic: الأعور‎‎, "the one-eyed"), was an Iranian general and governor during the Abbasid caliphate. Specifically, he served under al-Ma'mun during the Fourth Fitna and led the armies that would defeat al-Amin, making al-Ma'mun the caliph. He was then rewarded as governor of Khorasan, which marked the beginning of the Tahirid dynasty.

Tahir was born in Pushang which was a village near the ancient city of Herat in Khorasan. He was from a dehqan noble family who had distinguished themselves since the Abbasid Revolution, and were previously awarded minor governorships in eastern Khorasan for their service to the Abbasids. His grandfather Ruzaiq was a mawla of Talha ibn Abd-Allah al-Khuza'i, an Arab nobleman from the Khuza'a tribe, who served as the governor of Sistan. Ruzaiq's son Mus'ab was the governor of Pushang and Herat. Mus'ab's son, Husayn, who was the father of Tahir, continued to his father's role as the governor of Pushang and Herat. Tahir later succeeded him as the governor of Herat and Pushang.
