The JutaÃÂ River () is a river in Amazonas state in north-western Brazil.
The river flows through the Juruá-Purus moist forests ecoregion. The Jutaàriver runs northeast before reaching its mouth on the southern bank of the Amazon River (Solimões section). It is west of the Juruá River, and is roughly parallel to the lower Juruá.
The Cujubim Sustainable Development Reserve, established in 2003, lies on either side of the river in the municipality of JutaÃÂ. It is the largest conservation unit in Amazonas and the largest sustainable development reserve in the world. Further downstream the river forms the boundary between the Rio JutaàExtractive Reserve, created in 2002, to the southeast and the JutaÃÂ-Solimões Ecological Station to the northwest.
