A total of 24 teams from 12 of the 45 EHF member associations participated in the 2011–12 Euro Hockey League. The association ranking based on the EHL country coefficients is used to determine the number of participating teams for each association:
The 24 teams were drawn into eight pools of three. In each pool, teams played against each other once in a round-robin format. The pool winners and runners-up advanced to the round of 16. Pools A, D, E, and F were played in Brasschaat, Belgium from 21 to 23 October 2011 and the other pools were played in Mülheim, Germany. If a game was won, the winning team received 5 points. A draw resulted in both teams receiving 2 points. A loss gave the losing team 1 point unless the losing team lost by 3 or more goals, then they received 0 points.
The round of 16 and the quarter-finals were played in Rotterdam, Netherlands from 6 to 9 April 2012 and the semi-finals, bronze medal match and the final were played in Amstelveen, Netherlands from 26 to 27 May 2012. If the score remained tied, the match went to extra time with the silver goal rule being enforced. Matches that remained tied at the end of extra time were settled by a penalty shoot-out.
