The Usa (Russian: Уса́; Komi: Усва, Usva) is a river in the northeast corner of European Russia that drains the Polar Urals southwest into the Pechora. The Polar Urals tend to the northeast and the Usa runs parallel to them. It is in the Komi Republic of Russia and the largest tributary of the Pechora, which it joins from the right. It is 565 kilometres (351 mi) long, with a drainage basin of 93,600 square kilometres (36,100 sq mi).^[1]
