Rio Urucuia is a river flowing through the northwestern region of Minas Gerais, Brazil, draining into the greater São Francisco River basin. This tropical freshwater system winds through the cerrado landscape of the Brazilian interior, offering anglers access to a diverse assemblage of native Neotropical fish species. The river's position within the São Francisco drainage makes it part of one of Brazil's most biologically rich river systems, home to numerous endemic and regionally significant fish. The surrounding riparian zone reflects the characteristic cerrado vegetation of central Brazil, with the river corridor supporting both aquatic and terrestrial biodiversity.
