Bauchi State is a State in northern Nigeria. Its capital is the city of Bauchi. The state was formed in 1976 when the former North-Eastern State was broken up. It originally included the area now in Gombe State, which became a distinct state in 1996.

The Abubakar Tafawa Balewa University is located in the capital city Bauchi.

What is now known as Bauchi was until 1976 a province in the then North-Eastern State of Nigeria. According to the 2006 census, the state has a population of 4,653,066.

Bauchi state has gone through tremendous transformation over the years. During the colonial era up to independence, it formed part of the Bauchi-Plateau of the then Northern Region, until the 1967 state creation exercise, when the Bauchi, Borno, and Adamawa provinces constituted the former North-Eastern State.

With the creation of Bauchi state in 1976, then comprising present Bauchi and Gombe states, it included 16 Local Government Areas. The number of Local Government Areas in the then Bauchi state was increased to 20 and later to 23. However, in 1997 when Gombe state was created out of Bauchi and additional local governments were created in the country, Bauchi state was left with 20 Local Government Areas as shown below.

Bauchi is a city in northeast Nigeria, the capital of Bauchi State, of the Bauchi Local Government Area within that State, and of the traditional Bauchi Emirate. The city has a population of 316,173 (2004). The Local Government Area covers an area of 3,687 km² and had a population of 493,810 at the time of the 2006 Census.

The city was founded by Yaqub ibn Dadi, the only non-Fulani flag-bearer of the Sokoto Empire. The name was derived from a hunter called Baushe, who advised Yaqub to build his city west of the Warinje mountain. In return Yaqub promised to name his city after the hunter.

Abubakar Tafawa Balewa is buried in the city, while the Yankari National Park is 110 KM from the state capital. The city lies on the Port Harcourt – Maiduguri railway line.

Bauchi was originally served by a narrow gauge 762 mm (2 ft 6 in) Light railway, but this was later converted to the normal gauge of 1,067 mm (3 ft 6 in).
