2021 WAFF U-23 Championship squads

The 2021 WAFF U-23 Championship was an international football tournament held in Saudi Arabia from 4 to 12 October 2021. It was the second edition of the U-23 age group competition organised by the West Asian Football Federation.

The eleven national teams involved in the tournament were required to register a squad of at most 23 players, including three goalkeepers. Only players in these squads were eligible to take part in the tournament. Players born on or after 1 January 1998 were eligible to compete in the tournament.

The full squad listings are below. The age listed for each player is on 4 October 2021, 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. Players in boldface were capped at full international level prior to being called up.
