2008–09 CONCACAF Champions League championship round
The 2008–09 CONCACAF Champions League championship round began on 24 February 2009. The draw for the championship round was held on 10 December 2008. In each round, teams will play their opponent once at home and once away. The four group winners from the group stage will play the second leg at home in the quarterfinals. The order of the home and away matches for the semifinals and finals were determined in the draw.
In all rounds, if two teams are tied after both legs the team with the most away goals is the winner. If the two teams are also tied in away goals, then two fifteen-minute halves of extra time are played. If the two teams are still tied in total goals after extra time, a penalty shootout determines the winner.
