Tehsil Attock is one of the six tehsils of Attock district. It spreads over an area of 1,350 square kilometres with a population of 500,770 (as per DCR 1998). The TMA comprises 11 Union Councils, 3 urban Union Councils and 8 rural Union Councils, with only one CO unit namely Attock. It is located on the north of Kala Chitta mountain range which separates it from the rest of the district. At the northern foot of Kala Chitta hills, Haro river runs up to river Indus. TMA Attock differs from all other parts of the district because of its geographic attributes. Its three well defined and quite distinct geographical tracts are: Chhachh, Sarwala and Nala. In the north of Attock Tehsil lies Hassanabdal Tehsil.

Attock was raised to the level of Municipal Committee in 1922. After the implementation of Punjab Local Government Ordinance 2001, it was given the status of TMA.
