Abu Muhammad al-Hasan al-Muhallabi (died 963) was an Arab statesman who served as the vizier of the Buyid amir Mu'izz al-Dawla.
Al-Muhallabi quickly rose to be a prominent figure at the Buyid court, and later became the companion of Abu Ja'far Saymari, the chief secretary of Mu'izz al-Dawla, who was the Buyid ruler of Iraq.
In 950/951, Mu'izz al-Dawla appointed Muhallabi as his vizier and gave him the title of ostadh.
Many of al-Muhallabi's soldiers died in the fighting and he only narrowly escaped capture, swimming to safety.
Prisoners were exchanged and 'Imran was made a vassal of the Buyids, being appointed as governor of the Batihah.
