2019 UEFA European Under-21 Championship

The 2019 UEFA European Under-21 Championship (also known as UEFA Under-21 Euro 2019) will be the 22nd edition of the UEFA European Under-21 Championship (25th edition if the Under-23 era is also included), the biennial international youth football championship organised by UEFA for the men's under-21 national teams of Europe. The final tournament will be hosted in Italy and San Marino in mid-2019, after their bid was selected by the UEFA Executive Committee on 9 December 2016 in Nyon, Switzerland.

A total of 12 teams will play in the tournament, with players born on or after 1 January 1996 eligible to participate.

Same as previous Under-21 Championships that were held one year prior to the Olympics, this tournament will serve as European qualifying for the Olympic football tournament, with the top teams of the tournament (number of teams to be confirmed) qualifying for the 2020 Summer Olympic men's football tournament, where they will be represented by their under-23 national teams with maximum of three overage players allowed.

Hosts
The Italian Football Federation confirmed that Italy would bid to host the tournament in 2019, which also involved the San Marino Football Federation. Hosts Italy and San Marino were announced at a meeting of the UEFA Executive Committee in Nyon on 9 December 2016.

Qualification
All 55 UEFA nations entered the competition, and with the hosts Italy qualifying automatically (the other co-hosts San Marino will not qualify automatically), the other 54 teams will compete in the qualifying competition to determine the remaining 11 spots in the final tournament. The qualifying competition, which will take place from March 2017 to November 2018, consists of two rounds:
 * Qualifying group stage: The 54 teams are drawn into nine groups of six teams. Each group is played in home-and-away round-robin format. The nine group winners qualify directly for the final tournament, while the four best runners-up (not counting results against the sixth-placed team) advance to the play-offs.
 * Play-offs: The four teams are drawn into two ties to play home-and-away two-legged matches to determine the last two qualified teams.

Qualified teams
The following teams qualified for the final tournament.

Note: All appearance statistics include only U-21 era (since 1978).
