2018 CONCACAF League
The 2018 CONCACAF League was the 2nd edition of the CONCACAF League, a football club competition organized by CONCACAF, the regional governing body of North America, Central America, and the Caribbean.
Herediano defeated Motagua in the final to win their first CONCACAF League, and qualified for the 2019 CONCACAF Champions League to join the 15 direct entrants. Olimpia were the title holders, but did not qualify for this tournament and were unable to defend their title, and consequently their streak of participating in all ten editions of the CONCACAF Champions League since 2008 ended.

- In the leagues of El Salvador, Guatemala, Honduras, and Panama, the champions with the worse aggregate record, and the runners-up with the better aggregate record, qualify. If there is any team which are finalists of both tournaments, the runners-up with the worse aggregate record qualify.

Draw
The draw for the 2018 CONCACAF League was held on 23 May 2018, 19:00 EDT, at the Pullman Hotel in Miami.
The draw determined each tie in the round of 16 between a team from Pot 1 and a team from Pot 2, each containing eight teams. The "Bracket Position Pots" contained the bracket positions numbered 1 through 8 corresponding to each tie. The teams from Pot 1 were assigned a bracket position from Pot A and the teams from Pot 2 were assigned a bracket position from Pot B. Teams from the same association could not be drawn against each other in the round of 16 except for "wildcard" teams which replaced a team from another association.
The seeding of teams were based on the CONCACAF Club Index. Each team qualified for the CONCACAF League based on criteria set by the respective associations, resulting in an assigned slot for each team. The CONCACAF Club Index, instead of ranking each team, was based on the on-field performance of the teams that have occupied the respective qualifying slots in the previous five editions of the CONCACAF League and CONCACAF Champions League. To determine the total points awarded to a slot in any single edition of the CONCACAF League or CONCACAF Champions League, CONCACAF used the following formula:
| Points per | Participation | Win | Draw | Stage advanced | Champions |
| CONCACAF Champions League | 4 | 3 | 1 | 1 | 2 |
| CONCACAF League | 2 | 3 | 1 | 0.5 | 1 |
The 16 teams were distributed in the pots as follows:
