The CONMEBOL Preolímpico (English: Pre-Olympic Tournament) is an international association football event in the South America region organized by CONMEBOL.

In 1960, teams from North and Central America also entered the tournament.

[1] Before 1984, only junior or non-professional players were allowed to participate.

[2][3] In 1987 the competition opened to any player who had not played in World Cup (whether a qualifying match or at the final tournament).

[1] Due to an International Olympic Committee ruling, since 1992, male competitors have been required to be under 23 years old, and since 1996, a maximum of three over-23-year-old players have been allowed per squad.
