The 2001–02 European Challenge Cup pool stage (known as the Parker Pen Shield for sponsorship reasons) was the opening stage of the sixth season of the European Challenge Cup, the second-tier competition for European rugby union clubs.

It began when Connacht hosted Narbonne on 28 September 2001 and ended with four matches on 13 January 2002.

The eight pool winners advanced to the knockout stage.

These teams then competed in a single-elimination tournament that ended with the final at the Kassam Stadium in Oxford on 26 May 2002.

All kickoff times are local to the match location.
