List of rivers in Roraima (Brazilian State).
The list is arranged by drainage basin, with respective tributaries indented under each larger stream's name and ordered from downstream to upstream. Roraima is located entirely within the Amazon Basin, most of the state is within the Branco River sub-watershed.
Roraima is one of the 26 states of Brazil. Located in the country's North Region, it is the northernmost and most geographically and logistically isolated state in Brazil. It is bordered by the state of Pará to the southeast, Amazonas to the south and west, Venezuela to the north and northwest, and Guyana to the east.
The history of the territory that is now Roraima, a state at the extreme north of present-day Brazil is recent, but not thereby simple. Invaded numerous times by the various countries interested in the region, the seldom-visited Roraima aroused little interest on the part of the Portuguese, especially after the arrival of the royal family in Rio de Janeiro. Meanwhile, the territory became coveted by other countries, including England, the Netherlands, and, especially, Spain.
