Masrur al-Balkhi (Arabic: مسرور البلخي; died 26 December 893[1]) was a senior military officer in the late-9th century Abbasid Caliphate.
[6] In 875 he replaced Musa ibn Bugha as the commander in charge of suppressing the Zanj Rebellion, and was named as the governor of al-Ahwaz, Basra, the Tigris districts, al-Yamama, and al-Bahrayn.
In an attempt to slow down Ya'qub's progress, he flooded the region around Wasit by breaching a dike on the Tigris; he then made his way toward the main government army at Sib Bani Kuma.
After the Abbasid forces were victorious, Masrur's role in the battle was acknowledged in a public statement, and he was awarded the estates of Abu al-Saj Dewdad, who had fought on the Saffarid side.
Muhammad ibn Masrur was appointed as governor of the Mecca Road by al-Muwaffaq in 879; he deputed his brother 'Ali to assume the post, but the latter was killed by tribesmen of the Banu Asad while en route to al-Mughithah.
