2023–24 UEFA Youth League

The 2023–24 UEFA Youth League was the tenth season of the UEFA Youth League, a European youth club football competition organised by UEFA.

The title holders were AZ, who defeated Hajduk Split 5–0 in the previous edition's final, but they were eliminated in the round of 16. Olympiacos beat Milan 3–0 in the final held at the Colovray Stadium in Nyon, Switzerland, to secure their first title in the competition and become the first Greek team to ever win a UEFA club competition.

Teams
A total of 64 teams from 35 of the 55 UEFA member associations entered the tournament. They were split into two sections, each with 32 teams.


 * UEFA Champions League Path: The youth teams of the 32 clubs which qualified for the 2023–24 UEFA Champions League group stage entered the UEFA Champions League Path. If there was a vacancy (youth teams not entering), it was filled by a team defined by UEFA.
 * Domestic Champions Path: The youth domestic champions of the top 32 associations according to their 2023 UEFA country coefficients entered the Domestic Champions Path. If there was a vacancy (associations with no youth domestic competition, as well as youth domestic champions already included in the UEFA Champions League path), it was first filled by the title holders should they have not yet qualified, and then by the youth domestic champions of the next association in the UEFA ranking.

Antwerp, Braga, Dinamo Minsk, Famalicão, İstanbul Başakşehir, Klaipėdos, Lazio, Lecce, Lens, Mainz, Newcastle, Pafos, Partizan, Sarajevo, Union Berlin, and Universitatea Craiova made their tournament debuts.
