The Uarini River (Portuguese: Rio Uarini) is a river of Amazonas state in north-western Brazil. It is a tributary of the Solimões River.
The Uarini River flows north through the 187,982 hectares (464,510 acres) Baixo Juruá Extractive Reserve, created in 2001.[1] It then flows in a roughly northeast direction, entering the Solimões near the town of Uarini.
