Tigre River

The Tigre River is a Peruvian tributary of the Marañón River, located west of the Nanay River. It can be traveled for about 125 miles (201 kilometers) from where it meets the Marañón River. The Tigre River starts where two Ecuadorian rivers, the Conambo and Pintoyacu, join together near the border of Peru.

This river flows across flat lands, like the Nanay River. Its mouth, or where it ends, is about 42 miles (68 kilometers) west of where the Ucayali River joins the Marañón River. After the Tigre, other short rivers such as the Parinari, Chambira, and Nucuray flow westward along the Marañón, sharing similar features with the Nanay.

The name "Tigre" means "tiger" in Spanish, and in this area it refers to the Jaguar, a large wild cat that lives in the region.
