2019 FIFA U-20 World Cup squads

The following is a list of all the squads of the national teams that participated in the 2019 FIFA U-20 World Cup. Each team had to name a preliminary squad of between 22 and 50 players. From the preliminary squad, the team had to name a final squad of 21 players (three of whom must be goalkeepers) by the FIFA deadline. 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. Players born on or after 1 January 1999 and on or before 31 December 2003 were eligible to compete in the tournament.
