The 1947 South American Championship was the 20th South American Championship for national teams, and was organized by CONMEBOL.

It marked the first time Ecuador hosted the tournament, which hosted all the matches in Estadio George Capwell in Guayaquil.

Argentina won the tournament to obtain their ninth South American title.

Each team played the teams in a single round-robin tournament, earning two points for a win, one point for a draw, and zero points for a loss.

The team with the most points at the end of the tournament will be crowned the champions.
