Bahram ibn Mafinna (Persian: بهرام بن مافنه), also known as al-'Adil ("the just one") was an Iranian statesman who served as the vizier of the Buyid ruler Abu Kalijar from 1025/6 to 1041/2.
Nevertheless, Abu Kalijar managed to gain control over Fars, and successfully defended his domains against his brother.
During his period as a vizier, Bahram's prominent talents as a general and an administrator, and tolerance against other religions, made him famous among the subjects of the Buyid state.
However, the financial obligations imposed on the people of Kerman convinced them that Buyid rule would be preferable.
