The Tupinambá (plural: Tupinambás) are one of the various Tupi ethnic groups that inhabit present-day Brazil, and who had been living there long before the conquest of the region by Portuguese colonial settlers. The name Tupinambá was also applied to other Tupi-speaking groups, such as the Tupiniquim, Potiguara, Tupinambá, Temiminó, Caeté, Tabajara, Tamoio, and Tupinaé, among others. Before and during their first contact with the Portuguese, the Tupinambás had been living along the entire Eastern Atlantic coast of Brazil.
In a sense, the name can be applied exclusively to the Tupinambás who once inhabited the right shore of the São Francisco River (in the Recôncavo Baiano, Bahia), and from the Cabo de São Tomé (in Rio de Janeiro) to the town of São Sebastião (in São Paulo). Their language survives today in the form of Nheengatu.
