Cantonments in Pakistan (Urdu: چھاؤنی، پاکستان) are permanent bases of the Pakistan Armed Forces, which are administered by Cantonment Boards under the control of the Military Lands & Cantonments Department (ML&C), Ministry of Defence, Government of Pakistan. Cantonments are established under and governed by the Cantonments Act 1924.
In recent times, the demographic character of most independence-era cantonments has changed, as they are no longer primarily "garrison" areas, and include significant civilian populations and private businesses. Based on the strength of civil population, the cantonments have been divided into three classes. Class I Cantonments, in which the civil population is 100,000 or more; Class II Cantonments, in which the civil population is 50,000 or more but less than 100,000; and Class III Cantonments, in which the civil population is less than 50,000.
