2003–04 European Shield

The 2003–04 European Shield (known as the Parker Pen Shield for sponsorship reasons) was the 2nd season of the European Shield, Europe's third-tier club rugby union competition below the Heineken Cup and European Challenge Cup. A total of 16 teams participated, representing five different countries.

This competition was contested between 12 first round losers from the 2003–04 European Challenge Cup plus 4 other Clubs entering directly into the 1st Round. The structure of the competition was a purely knockout format; teams played each other on a home and away basis, with the aggregate points winner proceeding to the next round. The final was a single leg.

The competition began on 10 January 2004 and culminated in the final at the Stadio Luigi Zaffanella in Viadana on 21 May 2004. Montpellier secured a victory over Viadana in the final and picked up their first piece of European Club silverware.
