Twin cities in the context of Tri-Cities (disambiguation)

The Islamabad–Rawalpindi metropolitan area, commonly referred to as Islamabad–Rawalpindi or the Twin Cities, is the fourth-largest metropolitan area of Pakistan, after Karachi, Lahore, and Faisalabad. With a population of over 5.7 million, it is the third-most populous metropolitan area in the Punjab region, the largest in northern Punjab, and fourth in the entire country. It consists of the twin cities of Islamabad and Rawalpindi; administratively within the Islamabad Capital Territory and the province of Punjab.

The area includes the Pothohar Plateau in northern Punjab, with and the colonial-era city of Rawalpindi, as well as the modern planned city of Islamabad. The region received a major boom with the construction of Islamabad as the capital city of Pakistan in the 1960s.

Rawalpindi, colloquially known as Pindi, is the third-largest city in the Pakistani province of Punjab, serving as the principal commercial and industrial hub of northern Punjab. It is the fourth-most populous city in Pakistan and ranks as the world's third-largest Punjabi-speaking metropolis (after Lahore and Faisalabad). Located along the Soan River in north-western Punjab, Rawalpindi lies adjacent to Pakistan's capital, Islamabad, and the two are jointly known as the "twin cities".

Located on the Pothohar Plateau of northern Punjab — a region known for its ancient heritage, for instance the city of Taxila, a UNESCO World Heritage Site — Rawalpindi was founded in 1493 and remained a small town of little importance, with local Punjabi Muslim tribes indirectly ruling it for larger empires, up until 1765 when it was captured by the Bhangi Misl. During the Sikh era, Rawalpindi transitioned from a small regional town into one of the major Punjabi cities, becoming a hub of trade and military. The city also became a cosmopolitan hub, housing various ethnic minorities as immigrants and refugees alongside the native Punjabi majority.
