The Nawabs of Dhanbari (Bengali: ধনবাড়ীর নবাব) were a Bengali aristocratic family of feudal landowners. The zamindari estate encompassed parts of the Tangail District, particularly around Dhanbari. Although their aristocratic status was lost with the East Bengal State Acquisition and Tenancy Act of 1950, the Dhanbari estate remains an important part of the history of Tangail and tourist attraction.
