Abu Sa'd Khusrau Shah (Persian: ابو سعد خسرو شاه), was the Buyid amir of Fars (1049 and 1051–1054).
His succession to the entire Buyid Empire was prevented by his brother Abu Mansur Fulad Sutun, who took control of Fars.
However, Abu Sa'd Khusrau was shortly forced back to Iraq due to increased hostility between the Turks and the Dailamite troops there.
The next year, a combined army of Arab and Kurdish tribes ravaged Ahvaz and its surrounding regions, but were later repelled by Al-Malik al-Rahim.
However, barely a week had passed before the citizens of Baghdad began to complain to the amir about looting committed by the Seljuk troops, and asked him to expel them out of the city.
