Mallabhum, also known as Mallabhoom (Bengali: মল্লভূম) was the kingdom ruled by the Malla kings of Bishnupur, primarily in the present Bankura district in India's state of West Bengal.

It is told that Mallabhum is the territory, which included Bankura, a part of Burdwan, Birbhum, Santhal Parganas, Midnapur and also a part of Purulia. The Malla Rajas ruled over the vast territory in the south-western part of present West Bengal and a part of southeastern Jharkhand.

The area around Bishnupur was called Mallabhum. The core area would cover present day Bankura police station area (excluding Chhatna), Onda, Bishnupur, Kotulpur and Indas. In olden days the term was used for a much larger area, which probably was the furthest extent of the Bishnupur kingdom. In the north it stretched from Damin-i-koh in Santhal Parganas to Midnapore in the south. It included the eastern part of Bardhaman and included parts of Chota Nagpur in the west.

According to O'Malley, the Rajas of Bishnupur were also known as Malla kings. Malla is a Sanskrit word meaning wrestler but there could be some links with the Mal tribes of the area, who had intimate connection with the Bagdis.
