2018–19 UEFA Youth League

The 2018–19 UEFA Youth League was the sixth season of the UEFA Youth League, a European youth club football competition organised by UEFA.

The final was played on 29 April 2019 at the Colovray Stadium in Nyon, Switzerland, between English side Chelsea and Portuguese side Porto. In their first appearance in the final, Porto won 3–1 and secured their first title in the competition, the first ever for a Portuguese team. Barcelona were the defending champions, but were eliminated by Chelsea in the semi-finals, in a rematch of the previous season's final.

Teams
A total of 64 teams from at least 32 of the 55 UEFA member associations may enter the tournament. They are split into two sections, each with 32 teams:
 * UEFA Champions League Path:  The youth teams of the 32 clubs which qualified for the 2018–19 UEFA Champions League group stage entered the UEFA Champions League Path. Should 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 2017 UEFA country coefficients entered the Domestic Champions Path. Should 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 had not yet qualified, and then by the youth domestic champions of the next association in the UEFA ranking.

For this season, 37 associations are represented.
