2017 CONCACAF League

The 2017 CONCACAF League (officially the 2017 Scotiabank CONCACAF League for sponsorship purposes) was the inaugural edition of the CONCACAF League, a football club competition organized by CONCACAF, the regional governing body of North America, Central America, and the Caribbean.

The tournament was created as part of a new CONCACAF club competition platform consisting of two tournaments (CONCACAF League and CONCACAF Champions League) and a total of 31 teams competing during the season (an increase from the previous 24 teams), with 16 teams competing in the CONCACAF League from August to October, and the winner of the CONCACAF League joining the 15 direct entrants competing in the CONCACAF Champions League from February to April. Details of the inaugural edition of the CONCACAF League was confirmed on 8 May 2017.

Olimpia defeated Santos de Guápiles in the final, and qualified for the 2018 CONCACAF Champions League.

Qualification
A total of 16 teams participate in the CONCACAF League:
 * Central American Zone: 13 teams (from six associations; ordinarily from seven associations, but Guatemalan teams were excluded from this season's tournament)
 * Caribbean Zone: 3 teams (from two or three associations)

Therefore, teams from either 8 or 9 out of the 41 CONCACAF member associations may participate in the CONCACAF League.

Central America
The 13 berths for the Central American Football Union (UNCAF) are allocated to the seven UNCAF member associations as follows: two berths for each of Costa Rica, El Salvador, Guatemala, Honduras, Panama, and Nicaragua, and one berth for Belize.

All of the leagues of Central America employ a split season with two tournaments in one season, so the following teams qualify for the CONCACAF League:
 * In the league of Costa Rica, the champions with the worse aggregate record, and the non-champions with the best aggregate record, qualify. If there is any team which are champions of both tournaments, the non-champions with the second best aggregate record qualify.
 * 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 (or any team which are runners-up of both tournaments), qualify. If there is any team which are finalists of both tournaments, the runners-up with the worse aggregate record qualify. If there are any two teams which are finalists of both tournaments, the semi-finalists with the best aggregate record qualify.
 * In the league of Nicaragua, both champions qualify. If there is any team which are champions of both tournaments, the runners-up with the better aggregate record (or any team which are runners-up of both tournaments) qualify.
 * In the league of Belize, the champions with the better aggregate record (or any team which are champions of both tournaments) qualify.

If teams from any Central American associations are excluded, they are replaced by teams from other Central American associations, with the associations chosen based on results from previous CONCACAF Champions League tournaments. For this season, the two teams from Guatemala were excluded due to the suspension of their federation by FIFA and were replaced by an additional team each from Panama and Honduras.

Caribbean
The three berths for the Caribbean Football Union (CFU) are allocated via the Caribbean Club Championship, a subcontinental tournament open to the clubs of all 31 CFU member associations. To qualify for the Caribbean Club Championship, teams have to finish as the champions or runners-up of their respective association's league in the previous season, but professional teams may also be selected by their associations if they play in the league of another country.

The runners-up, third-placed and fourth-placed teams of the Caribbean Club Championship qualify for the CONCACAF League.

Teams
The following 16 teams (from eight associations) qualified for the tournament.
