Which South American capital is crossed by the Mapocho River?

The South American capital crossed by the Mapocho River is Santiago, Chile.

The Mapocho flows westward from the Andes through the Santiago metropolitan area, dividing the capital and passing landmarks such as Cerro San Cristóbal, Parque Forestal, Mercado Central, and the Museo Nacional de Bellas Artes. Its channel and bridges are prominent features of the city’s landscape.

The river begins in the Andes at the meeting of the San Francisco and Molina rivers. The Molina is fed by meltwater from the Iver Glacier on Cerro El Plomo. After crossing urban Santiago, the Mapocho continues west and eventually empties into the Maipo River.

The Mapocho is more than a geographic marker. It helped shape Santiago’s historical development, served as the city’s northern boundary until the 19th century, and remains an important environmental and flood-management concern. It is not associated with Lima, Quito, or Caracas.
