2017–18 UEFA Women's Champions League

Association team allocation

• Associations 1–12 each have two teams qualify.
• All other associations, should they enter, each have one team qualify.
• The winners of the 2016–17 UEFA Women's Champions League are given an additional entry if they do not qualify for the 2017–18 UEFA Women's Champions League through their domestic league. Since the title holders Lyon qualified through their domestic league, the additional entry for the Champions League title holders was not necessary for this season.

  Association ranking

;Notes – Additional berth for title holders – Did not enter – No rank Distribution The format of the competition remained unchanged from previous years, starting from the qualifying round, followed by the knockout phase starting from the round of 32. Unlike the men's Champions League, not every association enters a team, and so the exact number of teams entering in each round can not be determined until the full entry list is known. In general, the title holders, the champions of the top 12 associations, plus the runners-up of highest-ranked associations receive a bye to the round of 32. All other teams enter the qualifying round, with the group winners plus a maximum of two best runners-up advancing to the round of 32. Teams A record total of 61 teams from 49 associations entered this season's competition. Two associations had no league as of 2016–17. Andorra's league was not played eleven-a-side. The champions of Armenia, Azerbaijan and Gibraltar did not enter. Georgia entered a team for the first time since 2010–11, while Luxembourg returned after a one-year absence. Among the entrants, 21 teams entered the round of 32: the champions and runners-up from associations 1–9 and the champions from associations 10–12. The remaining 40 teams entered the qualifying round: the runners-up from associations 10–12 and the champions from the 37 associations ranked 13 or lower. ;Legend TH: Women's Champions League title holders CH: Domestic league champions RU: Domestic league runners-up ;Notes Round and draw dates UEFA has scheduled the competition as follows.
