Each participating team must submit a list of 40 players, including no fewer than four goalkeepers, thirty days before the opening match. This must be reduced to a final squad of 23 players by 26 May 2013. Players born no earlier than 1 January 1990 are eligible for the tournament, meaning some participants will be 23 years old as the 'under-21' limit applies 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.
Russia named their squad on 28 May 2013. Alan Dzagoev, Oleg Shatov and Aleksandr Kokorin were all named despite having to miss the opening game in order to play for the full international side. Kokorin was ruled out with injury on 31 May, while Shatov was subsequently released from the senior squad for the start of the tournament.
