Bulandshahr (Hindi:बुलंदशहर, Urdu: بلند شہر) is a city and a municipal board in Bulandshahr district in the state of Uttar Pradesh, India. It is the administrative headquarters of Bulandshahr District. According to Government of India, the district Bulandshahr is one of the Minority Concentrated District in India on the basis of the 2001 census data on population, socio-economic indicators and basic amenities indicators.

The history of Kurawali Distt.-Mainpuri (U.P.) begins even before 1200 BCE. This region is close to the capital of the Pandavas - Indraprastha and Hastinapur. After the decline of Hastinapur, Ahar, which is situated in the north-east part of Bulandshahr District, became an important place for the Pandavas.

Later the king Parma made a fort in this part of the region. A Tomar king named Ahibaran laid the foundation of a fort called Baran here and established his capital. It was traditionally called Baran city and only recently came to be called Bulandshahr in official usages. Since it was perched on a highland it came to be known as "high city" (Persian: بلند شهر‎), which translates as Bulandshahr in Persian language. There is a present day place called Upper Court (Hindi: ओपरकोट) which is believed to be the Fort of Raja Ahibarna and old Baran was limited to this area.
