West Pakistan (Urdu: مغربی پاکستان‎, Mag̱ẖribī Pākistān IPA: [məɣrɪbiː pɑːkɪst̪ɑːn]; Bengali: পশ্চিম পাকিস্তান, Pôśchim Pākistān) was one of the two exclaves created at the formation of the modern State of Pakistan following the 1947 Partition of India.

After gaining independence from the British in 1947, the State of Pakistan was physically separated into two exclaves, with the western and eastern wings separated from each other by the Republic of India. The western wing of Pakistan comprised three Governor's provinces (North-West Frontier, West-Punjab and Sindh Province), one Chief Commissioner's province (Baluchistan Province), and the Baluchistan States Union along with several other independent princely states (notably Bahawalpur, Chitral, Dir, Hunza, Khairpur and Swat), the Federal Capital Territory around Karachi, and the tribal areas. The eastern wing of the new country – East Pakistan – formed the single province of East Bengal (including the former Assam district of Sylhet).
