Also known as: Aquiri River, Rio Acre

Acre River, river, chiefly in western Brazil, rising on the Peruvian border, along which it continues eastward to form part of the Brazil–Bolivia border. Turning north at BrasilĂ©ia, the remainder of its 400-mi (645-km) course flows in a north-northeasterly direction, through the Brazilian states of Acre and Amazonas, to join the Rio Purus, a tributary of the Amazon, at BĂŽca do Acre. It was formerly called the Aquiri.
