The Denmark national under-21 football team has played since 1976 and is controlled by the Danish Football Association. Before 1976, the age limit was 23 years.
Because of the age restriction, a player can't be in the team for very long and the most promising young players spend little time with the under-21 team before making their senior national team debut.
Note:Club(s) represents the permanent clubs during the player's time in the under-21 national team. Players in bold have played at least one game for the senior Danish national team.
