The Jurua River (Portuguese Rio Jurua ; Spanish Rio Yurua ) is a southern affluent river of the Amazon River west of the Purus River , sharing with this the bottom of the immense inland Amazon depression, and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses.

For most of its length, the river flows through the Purus varzea ecoregion. [6] This is surrounded by the Jurua-Purus moist forests ecoregion. [7] It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1,133 km (704 mi) above its junction with the Amazon. It has a total length of approximately 3,283 km (2,040 mi), and is one of the longest tributaries of the Amazon.

The 251,577 hectares (621,660 acres) Medio Jurua Extractive Reserve , created in 1997, is on the left bank of the river as it meanders in a generally northeast direction through the municipality of Carauari . [8] The lower Jurua River forms the western boundary of the 187,982 hectares (464,510 acres) Baixo Jurua Extractive Reserve , created in 2001. [9] Since 2018, the lower portion of the river in Brazil has been designated a protected Ramsar site . [10]
