Allied Bank Limited is the fifth largest commercial bank in Pakistan and is a subsidiary of Ibrahim Group.

Allied Bank, with its registered Office in Lahore, is one of the largest banks within the country with over 1350 branches and ATMs. It was the first Muslim bank established in Pakistan before independence (1942) with the name of Australasia Bank. It was named as Allied Bank of Pakistan from Australasia Bank Limited in 1974, and Sarhad Bank Ltd, Lahore Commercial Bank Ltd and Pak Bank Ltd were also merged in it.

ABL is the first Muslim Bank established on territory that later on became Pakistan. It was established on December 3, 1942, as Australasia Bank at Lahore with capital of 0.12 million by Kashmiri silk trader Khawaja Bashir Baksh.

The bank's history is divided into many phases. During 25 years of united Pakistan the bank advanced forward in all areas of its activities. 1970's were a difficult decade for all banks of Pakistan. In 1971 East Pakistan was separated and Australasia Bank lost its 50 branches and a lot of capital as well. Nevertheless, the growth remained steady.

In 1974, all the banks were nationalized including Australasia Bank. The small provincial banks were merged into Australasia Bank. On 1 July 1974 the new entity was renamed as Allied Bank of Pakistan Limited. Then it started its operations as a public sector financial institution.
