Bauchi State (Fula: Leydi Bauchi 𞤤𞤫𞤴𞤣𞤭 𞤦𞤢𞤵𞤷𞥅𞤭) is a state in the North-East geopolitical zone of Nigeria. It is bordered by Jigawa to the north, Yobe to the northeast, Gombe to the east, Taraba and Plateau to the south, Kaduna to the west and Kano to the northwest. It takes its name from the historic city of Bauchi, which also serves as its capital. The state was formed in 1976 when the former North-Eastern State was broken up. It originally included the area that is now Gombe State, which became a distinct state in 1996.

Of the 36 states, Bauchi is the fifth largest in area and also the fifth most populous, with an estimated population of over 8,308,800 as of 2022. Geographically, the state is divided between the West Sudanian savanna in the south and the drier, semi-desert Sahelian savanna in the north with a small part of the montane Jos Plateau in the southwest. A key defining characteristic of the state’s landscape is Yankari National Park, a large wildlife park in southern Bauchi State that contains large populations of waterbuck, African buffalo, patas monkey, hippopotamus, roan antelope, and western hartebeest along with some of Nigeria's last remaining West African lion, African leopard and African bush elephant populations.

What is now Bauchi State has been inhabited for years by various ethnic groups, including the Bolewa, Butawa, and Warji in the central region; the Fulani, Kanuri, and Karai-Karai in the north; the Bankal, Jaku and Gerawa in and around the city of Bauchi; the Zaar and the Gwak in the south; the Dugurawa in the southeast; and the Jarawa in the southwest. Religiously, the vast majority of the state's population (~80%) are Muslim with smaller Christian and traditionalist minorities at about 15% and 5%, respectively. Evangelicals are the dominant Christian denomination but there are also adherents of the Roman Catholic faith. The Anglican Diocese of Bauchi is part of the Province of Jos, within the Church of Nigeria.

As a major agriculture-based state, the Bauchi State economy partially relies on livestock and crops, such as cotton, groundnuts, millet, tomatoes, and yams with advanced irrigation schemes increasing agricultural production since statehood. Other industries include food processing and canning facilities, tin and columbite mining, and tourism in Yankari National Park and its Wikki Warm Springs.

According to tradition, it was named after a hunter known as Baushe, who settled in the region before the arrival of Yakubu, the first traditional ruler of the Bauchi emirate (founded 1800–10). Bauchi and Adamawa were the two main sources of freedom and tourism for the Fulani empire of Sokoto.

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.

In the early 1800s, the Fulani jihad seized much of modern-day Bauchi State and formed the Bauchi Emirate under the Sokoto Caliphate. About 90 years later, a British expedition occupied the Emirate and incorporated it as Bauchi Province into the Northern Nigeria Protectorate which later merged into British Nigeria before becoming independent as Nigeria in 1960. Originally, modern-day Bauchi State was a part of the post-independence Northern Region until 1967 when the region was split and the area became part of the North-Eastern State. After the North-Eastern State was split, Bauchi State was formed on 3 February 1976 alongside ten other states.

Twenty years after statehood, a group of LGAs in the state's west was broken off to form the new Gombe State.

With the creation of Bauchi State in 1976, then comprising present Bauchi and Gombe State, 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 State has gone through a tremendous transformation over the years. The Ajawa language was spoken in Bauchi State, but became extinct by 1940 as speakers shifted to Hausa. Sharia law was adopted in June 2001.

Bauchi State consists of twenty Local Government Areas (LGAs). They are:

Bauchi State occupies a total land area of 49,119 km (18,965 sq mi) representing about 5.3% of Nigeria's total land mass and is located between latitudes 9° 3' and 12° 3' north and longitudes 8° 50' and 11° east.

The state is bordered by seven states, Jigawa to the north, Taraba for 54 km and Plateau for 360 km (220 mi) to the south, Gombe for 277 km (172 mi) to the east, Yobe for 188 km (117 mi) to the north-east, Kaduna to the west for 32 km (20 mi), and Kano for 131 km (81 mi) to the north-west.

Bauchi state is one of the states in the northern part of Nigeria that span two distinctive vegetation zones, namely, the Sudan savannah and the Sahel savannah. The Sudan savannah type of vegetation covers the southern part of the state. Here, the vegetation gets richer and richer towards the south, especially along water sources or rivers, but generally, the vegetation is less uniform and grasses are shorter than what grows even farther south, that is, in the forest zone of the middle belt.

The Sahel type of savannah, also known as semi-desert vegetation, becomes manifest from the middle of the state as one moves from the state's south to its north. This type of vegetation comprises isolated stands of thorny shrubs.

On the other hand, the southwestern part of the state is mountainous as a result of the continuation of the Jos Plateau, while the northern part is generally sandy.

The vegetation types as described above are conditioned by the climatic factors, which in turn determine the amount of rainfall received in the area. For instance, the rainfall in Bauchi state ranges between 1,300 millimetres (51 in) per annum in the south and only 700 millimetres (28 in) per annum in the extreme north. This pattern is because in the West Africa sub-region, rains generally come from the south as they are carried by the south-westerlies. There is therefore a progressive dryness towards the north, culminating in the desert condition in the far north. So also is the case in Bauchi state.

Consequently, rains start earlier in the southern part of the state, where rain is heaviest and lasts longer. Here the rains start in April with the highest record amount of 1,300 millimetres (51 in) per annum. In contrast, the northern part of the state receives the rains late, usually around June or July, and records the highest amount of 700 millimetres (28 in) per annum.

In the same vein, the weather experienced in the south and the north varies considerably. While it is humidly hot during the early part of the rainy season in the south, the hot, dry and dusty weather lingers up north.

In addition to rainfall, Bauchi state is watered by a number of rivers. They include the Gongola and Jama'are rivers.

The Gongola River crosses Bauchi state in Tafawa Balewa Local Government Area in the south and in Kirfi and Alkaleri Local Government Areas in the eastern part of the state, while the Jama’are River cuts across a number of Local Government Areas in the northern part of the state. Moreover, a substantial part of the Hadeja-Jama'are River basin lies in Bauchi state, which along with various fadama (floodplain) areas in the state provides suitable land for agricultural activities. These are further supported by the number of dams meant for irrigation and other purposes. These include the Gubi and Tilde-Fulani dams. There are also lakes such as the Maladumba Lake in Misau Local Government Area that further provide the necessary conditions to support Agriculture.

Bauchi has an oppressive wet season while the dry season is partly cloudy, and it is hot year-round. Over the year, the temperature also varies.

Like every other state in Nigeria, Bauchi state has not been spared in devastating effects of climate change. On 11 July 2022, the acting Director-general of the Bauchi State Emergency Management Agency (BASEMA), Mr Bala Lame, said "No fewer than 100 houses and several farmlands have been destroyed by devastating floods in Darazo LGA of the state". This he attributed to flooding after three days of persistent rainfall in the area. The average annual temperature ranges from 57 to 100 degrees Fahrenheit, with occasional exceptions when it falls below 51 or rises over 104.

The greatest time of year to visit Bauchi for warm-weather activities, according to the tourist score, is from early December to early February.

From 28 February to 10 May is the hot season, which lasts 2.5 months and has an average daily high temperature of over 96 °F. Averaging a high of 99 °F and a low of 74 °F, April is the hottest month of the year in Bauchi.

From 15 July to 1 October, the cool season, which has an average daily high temperature below 86 °F, lasts for 2.6 months. With an average low of 58 °F and high of 90 °F, January is the coldest month of the year in Bauchi.

Particulate matter, which has a diameter of less than 10 microns and is 1/7th the thickness of a human hair, is a significant source of air pollution in Bauchi. These particles, which can include smoke, soot, dust, salt, acids, and metals, pose a serious threat to health because they may be inhaled into the deepest parts of the lungs.

Gully erosion, which has swept away bridges, culverts, and homes, is causing alarm among residents of the settlements of Alkaleri and Kirfi in Bauchi State.

Bauchi State has a total of 55 tribal groups which include Gerawa, Sayawa, Jarawa, Kirfawa, Turawa Bolewa, Karekare, Kanuri, Fa'awa, Butawa, Warjawa, Zulawa, Boyawa MBadawa.

There are cultural similarities in the people's language, occupational practices, festivals, dress and there is a high degree of ethnic interaction especially in marriage and economic existence. Some of the ethnic groups have joking relationships that exist between them, e.g. Fulani and Kanuri, Jarawa and Sayawa, etc.

The Durbar Festival is a major annual attraction.

The Abubakar Tafawa Balewa University is located in the capital city Bauchi. Other educational institutions located in the state include Bauchi State University, Abubakar Tatari Ali Polytechnic, Federal Polytechnic, Bauchi and Federal university of health science Azare.
