The knockout stage of UEFA Euro 1988 was a single-elimination tournament involving the four teams that qualified from the group stage of the tournament. There were two rounds of matches: a semi-final stage leading to the final to decide the champions.
Any game in the knockout stage that was undecided by the end of the regular 90 minutes was followed by thirty minutes of extra time (two 15-minute halves). If scores were still level after 30 minutes of extra time, there would be a penalty shootout (at least five penalties each, and more if necessary) to determine who progressed to the next round.
The knockout stage began with the semi-finals on 21 June and ended with the final on 25 June 1988 at the Olympiastadion in Munich. The Netherlands won the tournament with a 2–0 victory over the Soviet Union.
