The
Bermejo River (
Spanish,
Río Bermejo) is a river in
South America that flows from
Bolivia to the
Paraguay River in
Argentina. The river is generally called Bermejo in spite of its different names along its way, but it also has its own
Native American names; in Wichí it is called
Teuco, and in
Guaraní it is called
Ypitá. In the plains of Argentina's
Gran Chaco the Bermejo forms
wetlands and splits into two branches. The southern branch is the bed of the old Bermejo River, now an
intermittent stream called Río Bermejito. The northern branch is now the
main stem of the Bermejo and is called the
Teuco River (
Río Teuco),
Bermejo Nuevo, or simply the Bermejo River. The two branches rejoin at , near
Villa Río Bermejito, forming the Lower Bermejo River.
