The 1920 South American Championship of Nations was the fourth continental championship for nations in South America.

The participating countries were the host Chile, Argentina, Uruguay and Brazil as the defending champion.

Ángel Romano was the top goalscorer alongside teammate José Pérez, with three goals, repeating his feat of three years earlier.

Brazil's 6–0 loss to Uruguay in this tournament would not be equaled until the 2014 FIFA World Cup, 94 years later, where they lost 7–1 against Germany.
