The Ribeira de Iguape River (Portuguese: Rio Ribeira de Iguape), or simply the Ribeira River[a] (Portuguese: Rio Ribeira), is a river of Paraná and São Paulo states in southeastern Brazil. It flows into the Atlantic Ocean near Iguape. The river is home to several endemic species of fish. So far no dams have been built on the river, although four have been proposed. Although it flows through a relatively sparsely populated region with untouched areas of Atlantic Forest, the river has been contaminated with heavy metals from mining beyond the point where it is considered safe to eat the molluscs found in the river and its estuary.
