The Borborema Plateau is a plateau in northeastern Brazil which extends across the states of Pernambuco, Paraíba, and Rio Grande do Norte. The plateau is the northeasternmost portion of the Brazilian Highlands and is the most relevant watershed of its region. It ranges approximately 400 kilometres (250 mi) from north to south and 200 kilometres (120 mi) from east to west. More than 100 rivers originate from the plateau, including the Moxotó, Mundaú, Pajeú, Paraíba do Norte, Seridó, and Una.
