Coordinates: 11°33′16″S 73°8′54.9″W / 11.55444°S 73.148583°W / -11.55444; -73.148583 The Urubamba River (Rio Urumamba) is a river in Peru. A partially navigable headwater of the Amazon River, it rises in the Andes to the south-east of Cuzco near the Puno Region border, where it is called the Vilcanota River (Rio Vilcanota). In the Sacred Valley, between Písac and Ollantaytambo, it is also called the Wilcamayu (sacred river). It flows north-north-west for 724 kilometers before coalescing with the lower Apurímac River to form the Ucayali River.

The Urubamba is divided into Upper Urubamba and Lower Urubamba, the dividing feature being the Pongo de Mainique, an infamous whitewater canyon.

John Walter Gregory, the British geologist, drowned in the river on June 2, 1932 while on a geological expedition to the Andes.

The economy is based on forestry and the nearby Camisea Gas Project. The main settlement in the region is the town of Sepahua.
