The Punjab Regiment is an infantry regiment of the Pakistan Army. The regiment takes its name from the historic Punjab region, which is now divided into the Punjab province of Pakistan and the Indian states of Punjab, Haryana and Himachal Pradesh. It was raised in its current form in 1956, following the amalgamation of the 1st, 14th, 15th and 16th Punjab regiments that were inherited by the Dominion of Pakistan from the British Indian Army upon the Partition of India. Since then, the regiment has expanded in size to 63 battalions.

The 1st Punjab Regiment was an infantry regiment of the British Indian Army from 1922 to 1947. Upon the Partition of India, it was transferred to the newly-raised Pakistan Army. It ceased to exist in this form in 1956, when it was amalgamated with the 14th, 15th and 16th Punjab regiments to form the Punjab Regiment, an existing infantry regiment of the Pakistan Army.
