Yaguas National Park, National park in Loreto Region, Peru.

Yaguas National Park is a protected area covering 868,000 hectares of Amazon rainforest in northern Peru with numerous rivers and wetlands. The landscape consists of dense forest vegetation and varied terrain that supports different types of ecosystems.

Yaguas was created as a reserved zone by Ministerial Resolution No. 161-2011-MINAM on 26 July 2011. On 10 January 2018 a supreme decree upgraded it to national park status. Its first master plan, covering 2021-2025, was approved on 19 April 2021 by Presidential Resolution No. 085-2021-SERNANP.

The park's name comes from the Yaguas, an indigenous people of the Loreto region after whom the area and its rivers are named. The reserve was created in 2011 partly to protect the headwaters of the Yaguas and other rivers that supply communities along the Putumayo. Visitors notice the blackwater rivers and flooded forest that local people know by name and use for fishing and transport.

The park lies in Loreto's Putumayo district and the Pebas, San Pablo and Ramón Castilla districts, near the Colombian border; access is by river from Iquitos via the Amazon, Napo and Putumayo. The first master plan 2021-2025 was approved by SERNANP presidential resolution 085-2021-SERNANP, so check current entry rules with SERNANP before travelling.

The waters within the park hold approximately 550 fish species, representing two-thirds of Peru's freshwater fish diversity. This extraordinary concentration of aquatic life makes it one of the world's most important sites for freshwater fish.
