This article lists the squads for the 2013 UEFA European Under-21 Championship. Only players born on or after 1 January 1990 were eligible to play. Each participating team had to submit a list of forty players, including no fewer than four goalkeepers, thirty days before the opening match. This then had to be reduced to a final squad of 23 players by 26 May 2013. Players born no earlier than 1 January 1990 were eligible for the tournament, meaning some participants were 23 years old as the 'under-21' limit applied at the start of the qualifying competition.
