This article lists the squads for the 2013 UEFA European Under-21 Championship that was hosted in Israel. 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.
Players in boldface have been capped at full international level at some point in their career.
† Players with a dagger had been given a full international cap by their country prior to the start of the tournament.
Age, caps, goals and club as of 5 June 2013.
