Doab (English: /ˈdoʊɑːb/) is a term used in South Asia for the tract of land lying between two confluent rivers. It is similar to an interfluve. In the Oxford Hindi-English Dictionary, R. S. McGregor refers to its Persian origin in defining it as do-āb (دوآب, literally "two [bodies of] water") "a region lying between and reaching to the confluence of two rivers." As per J. S. Grewal, a doab is "the inter-fluvial area between any two rivers".
