Serra Do Cachimbo

Serra do Cachimbo () is a low mountain range in the southern part of the state of Pará, Brazil. It is located mostly in the municipalities of Altamira, Itaituba, Jacareacanga, and Novo Progresso.

The Serra do Cachimbo complex is partly a continuous mass of mountains with a south west alignment, partly plateau with flat-bottomed valleys.
Altitude ranges from above sea level.
Erosion has created ridges and ravines. In the northern part there are escarpments along the transition to the peripheral depression of southern Pará, where the rivers descend in rapids and waterfalls such as the Salto do Curuá.

The Nascentes da Serra do Cachimbo Biological Reserve covers part of the range.
The southwest of the Rio Novo National Park is dominated by the Serra do Cachimbo, rising to , with a sharp escarpment forming its northern face.
The Iriri River and its tributaries (notably Curuá River) rises in the Serra do Cachimbo and flows for before joining the Xingu River. It is the main river of the Terra do Meio Ecological Station. The Jamanxim River, a tributary of the Tapajós, also rises in the Serra do Cachimbo. Jamanxim, Curuá and other rivers of Serra do Cachimbo are home to many endemic fish. Several of these are threatened by habitat loss and proposed dams,Netto-Ferreira, A.L. (2012)

Serra do Cachimbo is very rich in birds with more than 380 registered species. This richness is in part explained by the diversity of habitats, as it is in a region mostly covered by Amazon rainforest, but the Serra also has isolated patches of Cerrado vegetation.Dantas Santos, M.P.; L. Fábio Silveira; and J.M. Cardoso da Silva (2011). Birds of Serra do Cachimbo, Pará State, Brazil. Revista Brasileira de Ornitologia 19(2):244–259.
