Itapecuru River

The Itapecuru River (Rio Itapecuru) is a river in the Maranhão state of northern Brazil.

Course
The Itapecuru originates in the southern part of the state, in the Serra do Itapecuru, which rises to 660 m, and flows northward to empty into Baía do Arraial, an arm of the larger Baía de São José. It is an important source of water for twenty cities in Maranhão, including São Luís. Some of the headwaters of the river are protected by the 437000 ha Mirador State Park, created in 1980.
