A maximum of 68 teams from 55
UEFA member associations were eligible to participate in the 2018–19 UEFA Women's Champions League. The association ranking based on the
UEFA league coefficient for women was used to determine the number of participating teams for each association: • Associations 1–12 each had two teams qualify. • All other associations, should they enter, each had one team qualify. • The winners of the
2017–18 UEFA Women's Champions League were given an additional entry if they did not qualify for the 2018–19 UEFA Women's Champions League through their domestic league.
Association ranking For the 2018–19 UEFA Women's Champions League, the associations were allocated places according to their 2017 UEFA league coefficients for women, which took into account their performance in European competitions from 2012–13 to 2016–17. For the first time Switzerland had two entries, replacing Scotland in the top 12 associations. ;Notes • TH – Additional berth for title holders • NR – No rank (association did not enter in any of the seasons used for computing coefficients) • DNE – Did not enter
Distribution The format of the competition remained unchanged from previous years, starting from the qualifying round (played as mini-tournaments with four teams in each group), followed by the knockout phase starting from the round of 32 (played as home-and-away two-legged ties except for the one-match final). Unlike the men's
Champions League, not every association entered a team, and so the exact number of teams entering in each round (qualifying round and round of 32) could not be determined until the full entry list was known. In general, the title holders, the champions of the top 12 associations, and the runners-up of highest-ranked associations (exact number depending on the number of entries) received a bye to the round of 32. All other teams (runners-up of lowest-ranked associations and champions of associations starting from 13th) entered the qualifying round, with the group winners and a maximum of two best runners-up advancing to the round of 32.
Teams A total of 60 teams from 48 associations entered the competition, with the entries confirmed by UEFA on 8 June 2018. An association must have an eleven-a-side women's domestic league (or in special circumstances, a women's domestic cup) to enter a team. Among the entrants: • 20 teams entered the round of 32: the champions and runners-up from associations 1–8 (including title holders Lyon) and the champions from associations 9–12. • 40 teams entered the qualifying round: the runners-up from associations 9–12 and the champions from the 36 associations ranked 13 or lower. As
KÍ Klaksvík failed to win the Faroe Islands league, their streak of having participated in every edition of the UEFA Women's Cup/Champions League have ended after 17 seasons. ;Legend • TH: Women's Champions League title holders • CH: Domestic league champions • RU: Domestic league runners-up ;Notes ==Round and draw dates==
