2020–21 European Rugby Challenge Cup preliminary stage

The 2020–21 European Rugby Challenge Cup preliminary stage is the first stage of the competition in what is the seventh season of the European Rugby Challenge Cup. The competition involves fourteen teams competing in a single league – with teams playing three opponents from another domestic competition home and away. The preliminary stage began on 11 December 2020 and was due to be completed on 23 January 2021.

The top eight ranked teams in the league will advance to the last 16 with the teams ranked fifth to eight in both pools of the Champions Cup.

Teams are awarded group points based on match performances. Four points are awarded 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.

The preliminary stage was suspended after two rounds on 11 January 2021.
