Ghazipur (Hindi: ग़ाज़ीपुर, Urdu: غازیپور‎, previously spelled Ghazeepore, Gauspur, and Ghazipour), is a city and municipal corporation in the state of Uttar Pradesh, India. Ghazipur city is the administrative headquarters of the Ghazipur district, one of the four districts that form the Varanasi division of Uttar Pradesh. The city of Ghazipur also constitutes one of the five distinct tehsils, or subdivisions, of the Ghazipur district. Hindu tradition associates Ghazipur with a Raja Gaadhi, father of Vishwamitra Maharshi, the great rishi regarded as a Hindu saint, but although the area was an administrative center since the Gupta Empire, Ghazipur probably derives its name from the sayyid Masud, given the title Ghazi, who defeated the local Raja and established a town around 1330 CE.
