West Punjab (Punjabi: ‎لہندا پنجاب‎; Urdu: مغربی پنجاب) was a province in the Dominion of Pakistan from 1947 to 1955.

The first Governor was Sir Francis Mudie with Iftikhar Hussain Khan as the first Chief Minister.

Nearly all of these minorities left West Punjab for India, to be replaced by large numbers of Muslims fleeing from the opposite direction.

The official language of West Punjab was Urdu but most of the population spoke Punjabi.

The linguist George Abraham Grierson in his multi volume Linguistic Survey of India (1904–1928) considered the various dialects up to then called "Western Punjabi", spoken in North, West, and South of Lahore in what is now Pakistani Punjab, as constituting instead a distinct language from Punjabi.
