Reasi district is one of the 8 newly created districts of the Indian state of Jammu and Kashmir. Reasi district is bordered by Udhampur district and Ramban district in the east, Jammu district in the south, Rajouri district in the west and by Kulgam district on the north.

Reasi is one of the oldest towns of the Jammu and Kashmir State. It was the seat of the erstwhile Bhimgarh State, said to have been established by Raja Bhim Dev somewhere in the 8th century. It remained an independent principality till 1822, when Raja Gulab Singh the then Governor(Raja) of Jammu hill region, under the Sikh empire, consolidated the small states. Up until 1948 Reasi was a District of Jammu Province, but in the first administrative reorganization of the State undertaken in 1948 the major part of the then district Reasi was merged with district Udhampur, while some areas became part of District Poonch (now Rajouri)

Reasi is located at a distance of 64 km from Jammu and is bounded by Tehsil Gool-Gulabgarh in the north, Tehsil Sunderbani and Kalakote of District Rajouri in the west, Tehsil Udhampur in the east, Tehsils Jammu and Akhnoor of District Jammu on the south. Reasi sub division has a population of 1,20,380 as per 2001 census with 25.57% Muslims and Hindu majority. Climatically a major part of this Sub-Division falls in sub-tropicalzone and the rest in temperate zone. Summers are generally warm and winters cold with snowfall on the high of the most beautiful thing about Reasi is that in summer the temperature of Reasi will be less than most of the districts in jammu and in winter its temperature will be higher than other districts in jammu. so this makes Reasi favourable for all kinds of people visiting there.

According to the 2011 census Reasi district has a population of 314,667, roughly equal to the nation of The Bahamas. This gives it a ranking of 570th in India (out of a total of 640).

An historical fort named as Bhimgarh Fort, but generally also known as ‘Reasi Fort’ is located in the town of Reasi on a hillock approximately 150 meters high. As per local lore initially the fort was made of clay which later on was reconstructed with stone masonry and was generally used by the royal family for taking shelter during emergencies. Presently the fort is in the charge of the Department of Archeology, J&K Government since 1989. Today the fort stands out as one of the important landmarks in the town. During the time this was damaged several times due to its age and natural violence. From time to the government understanding the importance of this fort has tried its best to reconstruct it. It’s due to this fact that this fort is still standing in Reasi and it adds shine to the Reasi city.

Being far away from Jammu–Udhampur–Srinagar Highway 1-A and somewhat inaccessible due to the hilly area, economic progress in the mostly hilly region of Reasi has been rather slow. With the commissioning of Salal Hydroelectric Project at Dhyangarh near Reasi, the economic activity of the area has picked up considerably. Construction work of this project was started in 1970 by the National Hydro-Electric Power Corporation (NHPC) and the project was commissioned in 1987 when the first stage of 345 Megawatt power station was completed and balance/second stage of the project with 345 MW was commissioned in 1995 making the total generation to 690 MW. Power from this project flows to the Northern Grid from where it is distributed to the states of J&K, Punjab, Haryana, Delhi, Himachal Pradesh, Rajasthan, Uttar Pradesh and Chandigarh.

Reasi district has two tehsils viz., Reasi and Gool-Gulabgarh comprising 239 and 60 villages respectively.

This district consists of 4 blocks: Arnas, Mahore, Reasi and Pouni. Each block consists of a number of panchayats.
