The knockout stage of the 2006–07 UEFA Cup began on 14 February 2007, culminating with the final at Hampden Park, Glasgow, on 16 May 2007. The knockout stage included the top three teams from each group in the previous stage and the third-placed teams from the 2006–07 UEFA Champions League group stage.
Each knockout round tie consisted of two-legged matches, home and away, in which the team with the higher aggregate score progressed to the next round, with the exception of the final, which was played over just one match at a neutral venue. In the event that the two teams' aggregate scores were tied, the team that scored more goals in their away leg would progress to the next round.
The knockout stage involved 32 teams: the 24 teams which qualified as the winners, runners-up and third-placed teams of each of the eight groups in the group stage, and the eight third-placed teams from the Champions League group stage.
