The Araguari River (Portuguese: Rio Araguari) is the primary river of Amapá state in north-eastern Brazil. It became famous among surfers when some decided to ride its constant tidal bore, characterizing waves that can last for several minutes.[2] In 2013, three dams were built in the river to generate hydroelectricity. The dams ended the tidal bore which altered the flow of water in the Amazon, and caused significant land erosion and damage to the Bailique Archipelago.[3]

The river flows through the Uatuma-Trombetas moist forests ecoregion.[5] The river defines the western boundary of the 460,353 hectares (1,137,560 acres) Amapá National Forest, a sustainable use conservation unit created in 1989.[6]
