The 2024–25 UEFA Champions League knockout phase began on 11 February with the knockout phase play-offs and ended on 31 May 2025 with the final at the Allianz Arena in Munich, Germany, to decide the champions of the 2024–25 UEFA Champions League. A total of 24 teams competed in the knockout phase, with 16 entering in the play-offs and 8 receiving a bye to the round of 16.
Times are CET/CEST, as listed by UEFA (local times, if different, are in parentheses).
Qualified teams.
The knockout phase involved the top 24 teams that qualified from the league phase. The top 8 teams received a bye to the round of 16, while teams finishing in positions 9 to 24 entered the knockout phase play-offs.
Format.
Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, then 30 minutes of extra time were played (the away goals rule was not applied). If the score was still level at the end of extra time, the winners were decided by a penalty shoot-out. In the final, which was played as a single match, if the score was level at the end of normal time, extra time would be played, followed by a penalty shoot-out if the score was still level.
Draw procedure.
<section begin=Format />
In the knockout phase, there was no country protection, with teams from the same association able to face each other in any round. Teams could also face opponents they played during the league phase.
The mechanism of the draws for each round was as follows:
In the knockout phase, teams from the same or nearby cities were not scheduled to play at home on the same day or on consecutive days, due to logistics and crowd control. To avoid such scheduling conflict, several adjustments were made: For the knockout phase play-offs and the round of 16, if the two teams were drawn to play at home for the same leg, the home match of the team that had the lower league phase ranking was moved from either Tuesday or Wednesday from a regularly scheduled time to an earlier time slot, to a different day, and/or at an alternative venue without clashing any other competition. For the quarter-finals and semi-finals, the order of legs of the tie involving the team with the lowest priority was reversed from the original draw.
Predetermined pairings.
The bracket structure for the knockout phase was partially fixed in advance using seeding, with a symmetrical pattern on both sides. Teams' positions in the bracket were determined by their final standings in the league phase, ensuring that higher-ranked teams face lower-ranked opponents in earlier rounds. As a result, certain sets of teams, such as the top two from the league phase, could not meet until the final.
The structure of each side of the bracket can be summarised as follows, with the exact pairings of the play-offs and round of 16 determined by a draw:

Seeding.

Once completed, all the seeded teams were drawn into a tie as their opponents.
