The knockout stage of the 2023 Copa Paulino Alcantara, the domestic cup competition of the Philippines, began on 29 September with the quarterfinals and is scheduled to end on 9 December 2023 with the final to be played at Rizal Memorial Stadium. Eight teams competed in the knockout stage, which includes six teams who have played in the Philippines Football League along with the University of the Philippines and CF Manila, which have never played in the said league.[1]
Each tie in the knockout stage, apart from the final, was played over two legs. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score is level, then 30 minutes of extra time will be played. If the score is still level at the end of extra time, the winners will be decided by a penalty shoot-out. In the final, which will be played as a single match, if the score is still level at the end of normal time, extra time will be played, followed by a penalty shoot-out if the score is still level after that.
The bracket was decided during the main draw held on 17 June 2023.[1][2] A third place match was supposed to be held on the same day as the final, but was later cancelled due to scheduling conflicts.[3]
