The Araguari River (Portuguese: Rio Araguari River) 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.
The river flows through the Uatuma-Trombetas moist forests ecoregion. 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.
