The former administrative units of Pakistan are states, provinces and territories which mainly existed between 1947 and 1975 when the current provinces and territories were established. The former units have no administrative function today but some remain as historical and cultural legacies. In some cases, the current provinces and territories correspond to the former units – for example the province of Punjab includes almost all the territory of the former province of West Punjab. At independence (i) Provinces of Pakistan (ii) Federal Capital Territory of Pakistan (iii) Princely States of Pakistan Between August 1947 and March 1948, the rulers of the following princely states (which had existed alongside but outside British India) acceded their states to Pakistan, giving up control of their external affairs, while all retaining internal self-government, at least to begin with. This was lost by stages, until by 1974 all of the states had been fully integrated into Pakistan.

The eastern wing comprised the single province of East Bengal, which included the Sylhet District from the former British Indian province of Assam as well as the Buddhist-majority Chittagong Hill Tracts awarded by the Radcliffe Commission. The politically dominant western wing united three Governor's provinces (North-West Frontier Province (NWFP), West Punjab and Sind), and one Chief Commissioner's Province (Baluchistan), also included were thirteen princely states and parts of Kashmir. In 1948, the area around Karachi was separated from Sind province to form the Federal Capital Territory. In 1950 the North-West Frontier Province was expanded to include the small states of Amb and Phulra and the name of West Punjab province was changed to Punjab. The Baluchistan States Union was formed in 1952 by the four princely states of southwest Pakistan. Thus, between 1947 and 1955, Pakistan comprised five provinces and one territory. The western wing eventually included thirteen princely states, one union of states, Gwadar enclave, Gilgit agency and parts of Kashmir: Gilgit Agency (former agency of Kashmir – after independence on 1 November 1947, using flag of Muslim League) Azad Jammu and Kashmir (after Kashmir War 1947~48 - using newly AJK
