The 2023 U-20 Copa CONMEBOL Libertadores (Spanish: Copa CONMEBOL Libertadores Sub-20 2023) was the 7th edition of the U-20 CONMEBOL Libertadores (also referred to as the U-20 Copa Libertadores), South America's premier under-20 club football tournament organized by CONMEBOL. It was held in Chile from 1 to 16 July 2023.
Peñarol were the defending champions, having won the 2022 tournament, but were unable to retain their title after losing to Boca Juniors in the semi-finals, leading them to play the third place match against Cerro Porteño, which they also lost but on penalties. Boca Juniors defeated Independiente del Valle 2–0 in the final to win their first U-20 Copa Libertadores title. As winners of the 2023 U-20 Copa Libertadores, Boca Juniors earned the right to play against AZ, the winners of the 2022–23 UEFA Youth League, in the 2023 Under-20 Intercontinental Cup.
Teams
The competition was contested by 12 teams: the title holders, the youth champions from each of the ten CONMEBOL member associations, and one additional team from the host association.
Brazil (BRA): The 2022 Supercopa do Brasil Sub-20 was to be played between the winners of the 2022 Campeonato Brasileiro Sub-20 and the 2022 Copa do Brasil Sub-20, however, Palmeiras were directly proclaimed champions of the Supercopa as it had won both the Campeonato Brasileiro and the Copa do Brasil, thus securing the Brazilian berth reserved for the Supercopa champions.
Paraguay (PAR): Paraguay's berth was decided in a final match between Olimpia, 2022 U-19 Torneo Apertura champions, and Cerro Porteño, 2022 U-19 Torneo Clausura champions.
