2019–20 Rink Hockey Euroleague

The 2019–20 Rink Hockey Euroleague is the 55th season of Europe's premier club roller hockey tournament organised by World Skate Europe-Rink Hockey Committee, and the 23rd season since it was renamed from European Champion Clubs' Cup to Euroleague.

Sporting CP were the defending champions, but they were eliminated in the group stage.

Association ranking
For the 2019–20 Rink Hockey Euroleague, the associations were allocated places according to their coefficient, which takes into account the performance of each association's representative teams in European competitions between the 2014–15 and the 2018–19 seasons. The coefficient is calculated by dividing the total of points accumulated by the number of participating teams.

Participation is reserved to teams from associations that have an effective capacity to organise annually their own national championships. They will all have at least one team entering the competition. To allocate the other nine places, the D'Hondt method was applied to the coefficient of each association. In case of withdrawals, priority would be given according to the order established by the D'Hondt method.

Round dates
The schedule of the competition is as follows.

Draw
The 16 teams were allocated into four pots, with the title holders, Sporting CP, being placed directly as head-team of the Group A. The other three seeded teams will be from the three top ranked federations according to these priorities:
 * 1) National champions of those leagues.
 * 2) Highest ranked teams.

In each group, teams played against each other home-and-away in a home-and-away round-robin format.

Group stage
The 16 teams were allocated into four pots, with the title holders, Sporting CP, being placed as seeded team in the Group A automatically. The other 3 seeded teams, Porto, Barcelona and Forte dei Marmi, were automatically placed in groups B, C and D, respectively. The rest of the teams were drawn into four groups of four, with the restriction that teams from the same association could not be drawn against each other.

In each group, teams played against each other home-and-away in a home-and-away round-robin format.

A total of six national associations were represented in the group stage.

Knockout phase
The knockout phase comprises a quarter-final round and a final four tournament with two semi-finals and a final. In the quarter-finals, group stage winners play against group stage runners-up (other than the one from their own group), the latter hosting the first of two legs. The winners qualify for the final four tournament, which will take place at the ground of one of the four finalists.
