2017–18 UEFA Youth League

The 2017–18 UEFA Youth League was the fifth season of the UEFA Youth League, a European youth club football competition organised by UEFA.

Barcelona won their second Youth League title following a win over Chelsea in the final.

Red Bull Salzburg were the defending champions, but were eliminated in the round of 16. Starting from this season, the UEFA Youth League title holders were given an automatic berth in the Domestic Champions path if there was a vacancy.

Teams
A total of 64 teams from 43 of the 55 UEFA member associations entered the tournament, with Albania, Latvia and Luxembourg entering for the first time. They were split into two sections:
 * The youth teams of the 32 clubs which qualified for the 2017–18 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.
 * The youth domestic champions of the top 32 associations according to their 2016 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.
