Rio Novo National Park is a national park in the state of Pará, Brazil.

National Parks are a legally-defined type of protected area of Brazil. The first parks were created in the 1930s with other parks being gradually added, typically protecting a natural monument such as a waterfall or gorge near to a coastal population centre. At least two early parks were later submerged by hydroelectric reservoirs. The first park in the Amazon rainforest was inaugurated in 1974. Today the national parks cover a huge area, particularly in the Amazon. However, many of them suffer from outstanding claims for compensation from former owners or users of the land, and many lack the management plans, physical infrastructure and personnel needed to support public visits. The responsible government agency does not have the capacity to provide services such as food and drink, souvenir sales and guided tours, and bureaucracy has delayed letting the private sector bid on providing such services.
