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

Sukkur is a city in the Pakistani province of Sindh along the western bank of the Indus River, directly across from the historic city of Rohri. Sukkur is the third largest city in Sindh after Karachi and Hyderabad, and 14th largest city of Pakistan by population. The city was originally founded by the Rai dynasty of Sindh. The modern city was built in the 1840s. New Sukkur was established during the British era alongside the village of Sukkur. Sukkur's hill, along with the hill on the river island of Bukkur, form what is sometimes considered the "Gate of Sindh".
