Abu Mansur Ali (Persian: ابو منصور علي) was twelfth Shah of Shirvan, ruling from 1034 to 1043.
Abu Mansur murdered his elder brother Manuchihr I with aid of his wife and rose to throne, also marrying her in January 1035.
In order to seal the peace with Shirvan, he agreed to marry Ali's sister Shamkuya.

The mint name Beylaqan honoring the name of Caliph Al-Qa'im suggests that Shirvanshah extended his domain to southwards.
