The 2019–20 European Rugby Challenge Cup pool stage is the first stage of the competition in what is the sixth season of the European Rugby Challenge Cup.
The pool stage begins on 15 November 2019 and is due to be completed on 18 January 2019.
Given the nature of the Continental Shield, a competition including developing rugby nations and Italian clubs not competing in the Pro14, the qualifying teams from this competition are automatically included in Tier 4.
Teams in the same pool will play each other twice, both at home and away in the group stage, that will begin in November 2019, and continue through to January 2020, before the pool winners and three best runners-up progressed to the quarter finals.
Teams will be awarded competition points, based on match result.
