Paraguay is a landlocked country in south-central South America, bordered by Bolivia to the northwest and north, Brazil to the northeast and east, and Argentina to the southeast, south, and west. The Paraguay River divides the country into two distinct geographic regions: the Región Oriental (Eastern Region) and the Región Occidental (Western Region), also known as the Chaco Boreal. The nation’s capital is Asunción.
The Eastern Region is an extension of the Brazilian Plateau, while the Chaco Boreal forms part of the Gran Chaco, a flat tropical region. Four-fifths of the country’s perimeter is traced by the Paraguay, Apa, Paraná, and Pilcomayo rivers.
