The Paranã River is located in the Goiás and Tocantins states, Brazil. It divides two regions – the Northeast and north-central Goiás. It is formed by tributaries that descend the Serra Geral, the mountains that divide eastern Goiás and Bahia. One of the most important tributaries is the Crixás, which has its source near Formosa.{{Citation needed|date=August 2009}} Farther to the north the Paranã becomes the main tributary of the Tocantins River on the right bank. Today it is crossed by a long concrete bridge between the municipalities of Iaciara and Nova Roma. It forms the valley which makes up a vast region called the Vão do Paranã Microregion.
