The 2022–23 UEFA Europa Conference League knockout phase began on 16 February with the knockout round play-offs and ended on 7 June 2023 with the final at the Fortuna Arena in Prague, Czech Republic, to decide the champions of the 2022–23 UEFA Europa Conference League.
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.
[2] The mechanism of the draws for each round was as follows: In the knockout phase, teams from the same or nearby cities (Roma and Lazio, Fenerbahçe and İstanbul Başakşehir, and Anderlecht and Union SG, who share the same stadium), the first team listed played in the Europa League were not scheduled to play at home on the same day, due to logistics and crowd control.
For the knockout round playoffs and a round of 16, since both teams were in the same pot and must play at home in a given leg, the home match of the team that was not the domestic cup or Europa Conference League winner, or lower domestic ranking (if neither is the domestic cup or Europa Conference League winner; i.e. Lazio and Anderlecht for this season), was moved from Thursday to Wednesday.
[3] For the quarter-finals and semi-finals, if the two teams were drawn to play at home for the same leg, the order of legs of the tie involving the team with the lowest priority was reversed from the original draw.
[4][5] The schedule was as follows (all draws were held at the UEFA headquarters in Nyon, Switzerland).
