Set within the lush green region, the district of Sahibganj, with a predominantly tribal population is a part of Santhal Pargana division and forms the eastern most tip of the division. The Rajmahal and Pakur subdivisions of old Santhal Pargana district were carved out on 17th May, 1983 to form Sahibganj district. Subsequently Pakur sub-division of Sahibganj district was carved out on 28th January, 1994 to constitute Pakur District.

         A large part of the district is hilly. The vast tract of land enclosed between hill ranges had been assigned a name- Damin-I-koh, which is a Persian word means ‘Skirts of the hills’. The region on the bank of the Ganges is fertile and richly cultivated.

The river Ganges forming the northern boundary of the district enters at its north western corner and journeys eastward up to Sakrigali where it takes a turn to the south and forms the southern boundary of the district up to a little beyond Radhanagar in Rajmahal subdivision. The river has been drifting gradually to the north and the Sahibganj town, which was once on the riverbank, is now about a mile away. The average width of the Ganges in the district is about 4 and half kilometers.

        Owing to large scale unscrupulous felling the region once known for its thick and extensive forests is now bereft of much of its jungle wealth. The Forest department has undertaken afforestation of these areas.
