Itaparaná River

The Itaparaná River is a river of Amazonas state in north-western Brazil. It is a tributary of the Ipixuna River.

The river flows through the Purus-Madeira moist forests ecoregion in its upper reaches. It flows through the Purus várzea ecoregion, where it joins the Ipixuna shortly before that river joins the Purus River.
