Rio Grande do Norte, literally "Large River of the North", pronounced is one of the states of Brazil, located in the northeastern part of the country, on the edge of the South American continent. Because of its geographic position, Rio Grande do Norte has a strategic importance. It is the land of the folklorist Câmara Cascudo and is second in the world having the purest air, second only to Antarctica, according to NASA. Its 410 km (254 mi) of sand, much sun, coconut palms and lagoons are responsible for the fame of beaches, such as the secluded white sandy shores of Praia de Cajueiro, Genibapu (to the north of the capital, Natal), with sand dunes reaching 50 m (164 ft) in height. The beach of Baía Formosa, the prettiest of the south coast, has falésias, stretches with reefs and very popular for surfing. To the south, the beach of Sagi, a little more rustic, has clear waters and small dunes. In Natal, beside beaches, there are other tourist attractions, such as the fortress of Reis Magos and the Parque das Dunas, the second largest urban park in the country.

Rio Grande do Norte is dominated by its coastline. The state is famed for its beaches and sand dunes, and the air is, according to NASA, the second-cleanest in the world after Antarctica.

Two climates predominate: humid tropical, in the oriental littoral, and semi-arid, in the remaining (most part) of the State (including the North coast). The rainforest which once covered most of Brazil's coast had its northern end in the south of Rio Grande do Norte; the area north of Natal, the capital, is under dunes, a kind of formation associated with semi-arid climate. The semi-arid climate is characterized not only by the low level but also the irregularity of rainfall; some years can go by with no or very little rain; most of the interior of the State is part of the Polygon of Droughts (an area which receives special attention from the federal government). There are also many mangroves in the state, and the interior is dominated by rainforest. Rocas Atoll in the Atlantic Ocean, 260 km Northeast of Natal, also belongs to the state of Rio Grande do Norte.
