Maheshpur Raj was a zamindari estate in India. It occupied a large area now a part of Maheshpur block, in Pakur district of Jharkhand, India. According to the chronicles of the ruling family, Maheshpur was earlier a part of the Sultanabad estate. In the 14th century, a dispute arose over succession among two brothers of Sultanabad. The fief was then divided into two parts, with younger brother Anku Singh occupying what came to be known as Handua estate, and the elder brother Banku Singh establishing the Maheshpur Raj.
