2018 AFC U-23 Championship squads

The following is a list of squads for each national team which competed at the 2018 AFC U-23 Championship. The tournament took place in China, between 9–27 January 2018. It was the third U-23 age group competition organised by the Asian Football Confederation. As the tournament was not held during the FIFA International Match Calendar, clubs were not obligated to release the players.
The sixteen national teams involved in the tournament were required to register a squad of 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 1995 were eligible to compete in the tournament.
The full squad listings are below. The age listed for each player is on 9 January 2018, the first day of the tournament. The nationality for each club reflects the national association 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 have been capped at full international level at some point in their career.
