The Rio Madeira Sustainable Yield Forest (Portuguese: Floresta de Rendimento Sustentado Rio Madeira) is a set of managed forests in the state of Rondônia, Brazil. Three sectors, A, B and C, were created in 1990 but only sectors B and C remain. The forests have not been managed in a sustainable manner.

The Rio Madeira A, B and C sustainable yield forests were created in 1990, among eight state forests created that year on the left bank of the Madeira River. The others were the Rio Vermelho A, B, C and D sustainable yield forests and the Rio Abunã Sustainable Yield Forest They covered an area of 587,207 hectares (1,451,020 acres). In 1992 the state of Rondônia agreed to implement the Agricultural and Forestry Plan of Rondônia (Planafloro) under a loan agreement with the International Bank for Reconstruction and Development (IBRD). However, during the 1990s the Rondônia government took no effective measures to implement the forests. The Rondônia executive has tended to see development and conservation as incompatible, and has placed development first, opening roads and waterways and allowing occupation and unsustainable use of land.

On 31 August 2000 the Instituto Nacional de Colonização e Reforma Agrária (INCRA – National Institute for Colonization and Agrarian Reform) transferred 19 federal public lands in state conservation units to the state government, including the Rio Madeira A, B and C sustainable yield forests. Law 233/00 of 2000 redefined zoning and eliminated about 70% of the protected areas. Three forests were reduced and three ignored, leaving 150,461 hectares (371,800 acres). The remaining forests were not protected and were subject to invasions. Since then, various people were given ownership documents in Rio Madeira B by INCRA or the Porto Velho department of agriculture. The Banco da Amazônia released funds for agricultural activities within the forests.

The Rio Madeira Sustainable Yield Forest (A) was created in the municipality of Porto Velho by Rondônia state decree 4.574 of 23 March 1990, with an area of about 63,812.50 hectares (157,684.1 acres). The land could be declared of public utility and expropriated if the management guidelines were not met. The Rondônia Institute of Land and Colonisation could enter into agreements with public and private enterprises to implement the technical and scientific purposes of the forest. This conservation unit appears to have disappeared after 2000.
