| Image Alt: | Evening sun reflects in the water of the Itaya River. The water is alive with islands of trees and other green vegetation. A rowboat and a painted shack are mirrored in the water; around them lumber is scattered haphazardly on the water's surface. The opposite bank of the river is on the horizon, verdant and thick with trees. |

The Itaya River is a tributary of the Amazon River via the Nanay River in northern Peru. The Itaya flows alongside the city of Iquitos and the district of Belén.
In Iquitos, a riverwalk and breakwater called Malecón Tarapacá overlooks the Itaya.[3] To the north of Malecón Tarapacá is Malecón Maldonado.[3]
The Itaya River is the namesake of the fan palm genus Itaya, which was first discovered on the river's bank.[4]
The 2012 floods of the Amazon, Itaya, and Nanay Rivers, amid the heaviest rains the region had endured in 40 years, left approximately 80,000 people homeless.[5] In April 2015, 11 hours of steady rain swelled the Itaya again, causing the Iquitos–Nauta highway to collapse at four points: kilometres 22, 22.2, 23, and 26.[6]
