2023–24 EPCR Challenge Cup pool stage

The 2023–24 EPCR Challenge Cup pool stage was the first stage of the 10th season of the EPCR Challenge Cup.

Structure
The pool stage draw took place on 21 June 2023. The complete fixture list was then announced on 13 July 2023. Teams in the same pool played other teams in the same pool, either at home or away, in the group stage. The top four teams in each pool progressed to the round of 16 as well as the fifth-ranked team from each Champions Cup pool.

Teams were awarded group points based on match performances; four points for a win, two points for a draw, one attacking bonus point for scoring four or more tries in a match and one defensive bonus point for losing a match by seven points or fewer.

In the event of a tie between two or more teams, the following tie-breakers were used, as directed by European Professional Club Rugby:


 * 1) Where teams have played each other
 * 2) The club with the greater number of competition points from only matches involving tied teams.
 * 3) If equal, the club with the best aggregate points difference from those matches.
 * 4) If equal, the club that scored the most tries in those matches.
 * 5) Where teams remain tied and/or have not played each other in the competition (i.e. are from different pools)
 * 6) The club with the best aggregate points difference from the pool stage.
 * 7) If equal, the club that scored the most tries in the pool stage.
 * 8) If equal, the club with the fewest players suspended in the pool stage.
 * 9) If equal, the drawing of lots will determine a club's ranking.
