2020 CONMEBOL Pre-Olympic Tournament

The 2020 CONMEBOL Pre-Olympic Tournament was the 13th edition of the CONMEBOL Pre-Olympic Tournament, the quadrennial, international, age-restricted football tournament organised by the Confederación Sudamericana de Fútbol (CONMEBOL) to determine which men's under-23 national teams from the South American region qualify for the Olympic football tournament.

In August 2018, CONMEBOL announced the return of the South American Pre-Olympic Tournament in 2020 with Colombia as the host country, after a 16-year absence. The last edition of this competition had been held in Chile in 2004. From the 2008 through the 2016 Summer Olympics, the two teams from South America were determined by the South American Youth Football Championship, always held in the previous year. The tournament was held from 18 January through 9 February 2020.

The top two teams qualified for the 2020 Summer Olympics men's football tournament in Japan as the CONMEBOL representatives. Argentina successfully defended their title won 16 years ago, and qualified for the Olympics together with runners-up Brazil, the defending Olympic champions.

Teams
All ten CONMEBOL member national teams entered the tournament.

Venues
Colombia was announced as host of the tournament at the CONMEBOL Council meeting held on 14 August 2018 in Luque, Paraguay. On 28 August 2019, Pereira, Armenia, and Bucaramanga were announced as the host cities.

Squads
Players born on or after 1 January 1997 were eligible to compete in the tournament.

Draw
The draw of the tournament was held on 5 November 2019, 19:00 COT (UTC−5), at the Auditorium of the Colombian Football Federation in Bogotá, Colombia. The ten teams were drawn into two groups of five. The hosts Colombia and Brazil as the current Olympic champions and best CONMEBOL team in the FIFA World Rankings as of October 2019 were seeded into Group A and Group B, respectively, and assigned to position 1 in their group, while the remaining eight teams were placed into four "pairing pots" based on their FIFA World Rankings as of October 2019 (shown in brackets). The positions of these eight teams within their groups were also defined by draw.

The draw was led by Hugo Figueredo, CONMEBOL's Director of Competitions, with the collaboration of Daniela Montoya, a member of the Colombia women's national football team, and former Colombian footballer Iván Valenciano.
