The 2019–20 UEFA Champions League qualifying phase and play-off round began on 25 June and will end on 28 August 2019.
A total of 53 teams compete in the qualifying system of the 2019–20 UEFA Champions League, which includes the qualifying phase and the play-off round, with 43 teams in Champions Path and 10 teams in League Path. The six winners in the play-off round (four from Champions Path, two from League Path) advanced to the group stage, to join the 26 teams that enter in the group stage.
Times are CEST (UTC+2), as listed by UEFA (local times, if different, are in parentheses).
NOTE: The following list of qualified teams is provisional, subject to final confirmation by UEFA in June 2019, as each participating team must obtain a UEFA club license. All qualified teams are included in this list as long as they have not been banned by UEFA or have not failed their final appeal with their football association on obtaining a license.
The Champions Path includes all league champions which do not qualify directly for the group stage, and consists of the following rounds:
Preliminary round (4 teams playing one-legged semi-finals and final): 4 teams which enter in this round.
First qualifying round (32 teams): 31 teams which enter in this round, and 1 winner of the preliminary round.
Second qualifying round (20 teams): 4 teams which enter in this round, and 16 winners of the first qualifying round.
Third qualifying round (12 teams): 2 teams which enter in this round, and 10 winners of the second qualifying round.
Play-off round (8 teams): 2 teams which enter in this round, and 6 winners of the third qualifying round.
All teams eliminated from the Champions Path enter the Europa League:
The 3 losers of the preliminary round and 15 of the 16 losers of the first qualifying round (excluding 1 team which receives a bye to the third qualifying round as decided by an additional draw held after the Champions League first qualifying round draw) enter the Champions Path second qualifying round.
Each tie, apart from the preliminary round, is played over two legs, with each team playing one leg at home. The team that scores more goals on aggregate over the two legs advance to the next round. If the aggregate score is level, the away goals rule is applied, i.e. the team that scores more goals away from home over the two legs advances. If away goals are also equal, then extra time is played. The away goals rule is again applied after extra time, i.e. if there are goals scored during extra time and the aggregate score is still level, the visiting team advances by virtue of more away goals scored. If no goals are scored during extra time, the tie is decided by penalty shoot-out. In the preliminary round, where single-match semi-finals and final are hosted by one of the participating teams, if scores are level at the end of normal time, extra time is played, followed by penalty shoot-out if scores remain tied.
In the draws for each round, teams are seeded based on their UEFA club coefficients at the beginning of the season, with the teams divided into seeded and unseeded pots containing the same number of teams. A seeded team is drawn against an unseeded team, with the order of legs (or the administrative "home" team in the preliminary round matches) in each tie decided by draw. As the identity of the winners of the previous round is not known at the time of the draws, the seeding is carried out under the assumption that the team with the higher coefficient of an undecided tie advances to this round, which means if the team with the lower coefficient is to advance, it simply take the seeding of its opponent. Prior to the draws, UEFA may form "groups" in accordance with the principles set by the Club Competitions Committee, but they are purely for convenience of the draw and do not resemble any real groupings in the sense of the competition. Teams from associations with political conflicts as decided by UEFA may not be drawn into the same tie. After the draws, the order of legs of a tie may be reversed by UEFA due to scheduling or venue conflicts.
A total of 32 teams were involved in the first qualifying round draw: 31 teams entering in this round, and the winners of the preliminary round. They were divided into three groups: two of ten teams, where five teams were seeded and five teams were unseeded, and one of twelve teams, where six teams were seeded and six teams were unseeded.
^Following a mistake with the original draw not following the correct procedure, UEFA performed a re-draw to establish the home team for each leg in the Ferencváros-Ludogorets Razgrad tie. As a result, the order of legs was reversed. The error did not affect any other tie.
A total of 24 teams were involved in the second qualifying round draw.
Champions Path: four teams entering in this round, and the 16 winners of the first qualifying round. They were divided into two groups of ten teams, where five teams were seeded and five teams were unseeded.
League Path: four teams entering in this round. Two teams were seeded and two teams were unseeded.
A total of 20 teams are involved in the third qualifying round draw.
Champions Path: two teams entering in this round, and the 10 winners of the second qualifying round Champions Path. Six teams are seeded and six teams are unseeded.
League Path: six teams entering in this round, and the two winners of the second qualifying round League Path. Four teams are seeded and four teams are unseeded. Teams from Ukraine and Russia could not be drawn into the same tie, and if such a pairing was drawn or was set to be drawn in the final tie, the second team drawn in the current tie would be moved to the next tie.
