Bukkur, Bakhar or Bhakkar is a historical city and an Island fort situated between Rohri and Sukkur in the Sindh province of Pakistan.

[2] The entirety of the island lies within the fort, as the fortification wall encircles the outer perimeter, bordering the Indus River on all sides.

Historical texts such as the Tuhfat al-Kiram suggest that the town did not exist during the Dahir's era nor is its name mentioned in the early Muslim period.

This fort, situated on the opposite side of the Indus River and belonging to Raja Dahir, was administered from the capital city of Aror.

It appears that during this period, the northern Deltaic Apex was situated northeast of Rohri-Sukkur, with a smaller channel passing through Aror and the main trunk-river flowing between Bakhar island and the hilly formation north of Sukkur city.

[8] The Samma Jam Nizamuddin II swiftly implemented measures upon ascending to the throne to counter the frequent invasions by Baloch tribes into Sindh.

He bolstered the fortifications of Bhakkar, stocked it with provisions, and appointed his slave, Dilshad, to oversee the fort's defense, thereby securing the northern borders of his realm.
