A total of 188 teams from 54 of the 55 UEFA member associations were expected to participate in the 2016–17 UEFA Europa League. The association ranking based on the UEFA country coefficients was used to determine the number of participating teams for each association:
Associations 1–51 each had three teams qualify.
* As the winners of the 2015–16 UEFA Europa League, Sevilla qualified for the 2016–17 UEFA Champions League; the 2016–17 UEFA Europa League berth they would otherwise have earned for finishing 7th in the 2015–16 La Liga was vacated and not passed to another Spanish team.
Associations 52–53 each had two teams qualify.
Liechtenstein and Gibraltar each had one team qualify.
Moreover, 33 teams eliminated from the 2016–17 UEFA Champions League were transferred to the Europa League.
The UEFA Executive Committee approved in December 2014 changes to the rewards given according to the Respect Fair Play ranking, and starting from the 2016–17 season, the three Fair Play berths were no longer allocated to the Europa League.
Association ranking
For the 2016–17 UEFA Champions League, the associations were allocated places according to their 2015 UEFA country coefficients, which took into account their performance in European competitions from 2010–11 to 2014–15. Apart from the allocation based on the country coefficients, associations could have additional teams participating in the Europa League, as noted below:
– Additional teams transferred from Champions League
– Vacated berth due to Europa League title holders playing in Champions League
;Notes
Distribution
In the default access list, Sevilla enter the third qualifying round. However, since they qualified for the Champions League as the Europa League title holders, the spot which they qualified for in the Europa League third qualifying round is vacated, and the following changes to the default allocation system are made:
The domestic cup winners of association 18 are promoted from the second qualifying round to the third qualifying round.
The domestic cup winners of associations 27 and 28 are promoted from the first qualifying round to the second qualifying round.

Redistribution rules
A Europa League place is vacated when a team qualifies for both the Champions League and the Europa League, or qualifies for the Europa League by more than one method. When a place is vacated, it is redistributed within the national association by the following rules :
When the domestic cup winners also qualify for the Champions League, their Europa League place is vacated. As a result, the highest-placed team in the league which have not yet qualified for European competitions qualify for the Europa League, with the Europa League qualifiers which finish above them in the league moved up one "place".
When the domestic cup winners also qualify for the Europa League through league position, their place through the league position is vacated. As a result, the highest-placed team in the league which have not yet qualified for European competitions qualify for the Europa League, with the Europa League qualifiers which finish above them in the league moved up one "place" if possible.
For associations where a Europa League place is reserved for the League Cup winners, they always qualify for the Europa League as the "lowest-placed" qualifier. If the League Cup winners have already qualified for European competitions through other methods, this reserved Europa League place is taken by the highest-placed team in the league which have not yet qualified for European competitions.
Teams
The labels in the parentheses show how each team qualified for the place of its starting round:
PW: End-of-season European competition play-offs winners
CL: Transferred from Champions League
*GS: Third-placed teams from group stage
*PO: Losers from play-off round
*Q3: Losers from third qualifying round
Notably two teams took part in the competition that were not playing in their national top division, Zürich and Hibernian. ;Notes

The 48 teams were drawn into twelve groups of four, with the restriction that teams from the same association could not be drawn against each other. For the draw, the teams were seeded into four pots based on their 2016 UEFA club coefficients. In each group, teams play against each other home-and-away in a round-robin format. The group winners and runners-up advance to the [|round of 32], where they are joined by the eight third-placed teams of the 2016–17 UEFA Champions League group stage.

Tiebreakers
The teams are ranked according to points. If two or more teams are equal on points on completion of the group matches, the following criteria are applied in the order given to determine the rankings :
higher number of points obtained in the group matches played among the teams in question;
superior goal difference from the group matches played among the teams in question;
higher number of goals scored in the group matches played among the teams in question;
if, after having applied criteria 1 to 4, teams still have an equal ranking, criteria 1 to 4 are reapplied exclusively to the matches between the teams in question to determine their final rankings. If this procedure does not lead to a decision, criteria 6 to 12 apply;
superior goal difference in all group matches;
higher number of goals scored in all group matches;
higher number of away goals scored in all group matches;
higher number of wins in all group matches;
higher number of away wins in all group matches;
lower disciplinary points total based only on yellow and red cards received in all group matches ;
In the knockout phase, teams play against each other over two legs on a home-and-away basis, except for the one-match final. The mechanism of the draws for each round is as follows:
In the draw for the round of 32, the twelve group winners and the four third-placed teams from the Champions League group stage with the better group records are seeded, and the twelve group runners-up and the other four third-placed teams from the Champions League group stage are unseeded. The seeded teams are drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same group or the same association cannot be drawn against each other.
In the draws for the round of 16 onwards, there are no seedings, and teams from the same group or the same association can be drawn against each other.
