Madeirinha River is a river of Mato Grosso and Amazonas states in north-western Brazil, a left tributary of the Roosevelt River.
Course
In Mato Grosso the river forms the western boundary of the Rio Madeirinha Ecological Station, a fully protected environmental unit created in 1997. It then flows north east through the Tucumã State Park in Mato Grosso and the Manicoré State Forest in Amazonas, a sustainable use conservation unit created in 2005. It continues north east from the state forest before joining the Roosevelt river.
