2014 Copa Libertadores knockout stage

The knockout stages of the 2014 Copa Libertadores de América were played from April 16 to August 13, 2014. A total of 16 teams competed in the knockout stages.

Qualified teams
The winners and runners-up of each of the eight groups in the second stage qualified for the knockout stages.

Seeding
The qualified teams were seeded in the knockout stages according to their results in the second stage, with the group winners seeded 1–8, and the group runners-up seeded 9–16.

Format
In the knockout stages, the 16 teams played a single-elimination tournament, with the following rules:
 * Each tie was played on a home-and-away two-legged basis, with the higher-seeded team hosting the second leg. However, CONMEBOL required that the second leg of the finals must be played in South America, i.e., a finalist from Mexico must host the first leg regardless of seeding.
 * In the round of 16, quarterfinals, and semifinals, if tied on aggregate, the away goals rule was used. If still tied, the penalty shoot-out was used to determine the winner (no extra time was played).
 * In the finals, if tied on aggregate, the away goals rule was not used, and 30 minutes of extra time was played. If still tied after extra time, the penalty shoot-out was used to determine the winner.
 * If there were two semifinalists from the same association, they must play each other.
