2023 FIFA U-20 World Cup squads

The 2023 FIFA U-20 World Cup was an international football tournament held in Argentina from 20 May to 11 June 2023. The 24 participating national teams were required to register a squad of 21 players, including at least three goalkeepers (Regulations Article 27.1). Only players in these squads were eligible to take part in the tournament. The tournament exclusively required players to be born between 1 January 2003 and 31 December 2007 to be eligible, that is, they had to be a maximum of 20 years old and at least 16 years old by the end of the calendar year in which the competition was played (Regulations Article 24.2).
Each participating national team had to submit a provisional list of a minimum of 35 and a maximum of 55 players (including at least four goalkeepers) to FIFA by the deadline stipulated by them (10 April 2023). The provisional lists were not published by FIFA and player changes were allowed only in exceptional cases (Regulations Article 25). The final list of 21 players per national team had to be submitted to FIFA by the deadline stipulated by them (10 May). All players in the final list had to be chosen from the respective provisional list. Players in the final squad could be replaced by a player from the preliminary squad due to serious injury or illness up to 24 hours prior to kickoff of the team's first match (Regulations Article 27).
FIFA published final lists of all teams on 12 May 2023.
The age listed for each player is on 20 May 2023, the first day of the tournament. The nationality for each club reflects the national association (not the league) to which the club is affiliated. A flag is included for coaches who are of a different nationality than their own national team. Player names marked in bold have been capped at full international level.
