The Japurá River or Caquetá River is a river about 2,820 kilometres (1,750 mi) long (some sources say 2,414 km) rising as the Caquetá River in the Andes in southwest Colombia. It flows southeast into Brazil, where it is called the Japurá. The Japurá enters the Amazon River through a network of channels. It is navigable by small boats in Brazil. Much of the jungle through which the eastern Caquetá originally flowed has been cleared for pasture, crops of rice, corn, manioc, and sugar cane, and in the past two decades, particularly coca crops.
