is a city in the Indian state of Uttar Pradesh and a part of the National Capital Region of Delhi. It is the administrative headquarters of Ghaziabad district and is the largest city in western Uttar Pradesh, with a population of 2,358,525. Well connected by roads and railways, it is a major rail junction for North India. It is sometimes referred to as the "Gateway of Uttar Pradesh" because it is close to New Delhi, on the main route into Uttar Pradesh. Recent construction works have led to the city being described by a City Mayors Foundation survey as the second fastest-growing in the world. Situated in the Upper Gangetic Plains, the city has two major divisions separated by the Hindon River, namely Trans-Hindon on the west and Cis-Hindon on the east.
