Forbesganj subdivision is an administrative subdivision out of two subdivisions of Araria district in the state of Bihar, India. It comprises 6 Blocks of Araria[1] The headquarter of the subdivision is in Forbesganj town.
During the British Raj the area was under the administration of a British district collector and municipal commissioner, Alexander John Forbes (1807-1890) of East India Company. Forbes had a bungalow at the same location. Consequently the area was known as 'residential area' also abbreviated as 'R-area'. Over time, the name transformed to 'Araria' and the neighbouring subdivision came to be known as 'Forbesganj'.[2]
Sub divisional Hospital Forbesganj is located near the Subdivision Office, Forbesganj[3] [4]
