Rio Novo National Park, National park in Pará, Brazil

Rio Novo National Park is a protected forest area in the Amazon region located between the municipalities of Novo Progresso and Itaituba in Para state. The land covers dense rainforest with numerous rivers, streams, and untouched sections that form a continuous woodland ecosystem.

The park was established by the Brazilian government in 2006 to protect Amazon forest systems and wildlife. This decision was part of a broader effort to preserve large forest areas from deforestation and industrial use.

The park adjoins the Mundurucu Indigenous Territory along its western boundary, and the name Rio Novo comes from the river formed where the Inambé and Marrom rivers meet. The park is open to visitors only with special permission, and an advisory council was set up on 8 November 2011.

Access is limited and requires permits from the park management authority. Visitors should plan ahead and work with local guides to navigate safely through the forest area.

The park's streams are largely contaminated by illegal mining in the region, and much of the park suffers from unregularized land tenure and illegal deforestation. The endangered white-cheeked spider monkey (Ateles marginatus) is endemic here, and the park adjoins the Mundurucu Indigenous Territory to the west.
