The Atuá River (Portuguese : Rio Atuá) is a river of Marajó, which itself is an island in the mouth of the Amazon. ^[2]

Its main tributary on the left is the Anabiju River. Close to the same location, the Muaná River branches off at its right hand side. Since the Atuá is relatively deep and navigable for most of its length, it fulfills an important role for transportation in the region. The Atuá enters the Pará River opposite the mouth of the Tocantins River. There are two islands close to its mouth, called Ilha do Palheta and Atuá Island. ^[3]

The banks of the Atuá are lined with grassy fields with some low trees. Their soils consist of sand and clay, and they are subject to flooding only during periods of heavy rainfall. ^[4]

A canal has been projected between the Atuá and the Anajás River to facilitate transport between Belém and Amapá, but it hasn't materialised. ^{[5] [6]}
