2007–08 European Challenge Cup pool stage

The 2007–08 European Challenge Cup pool stage was the opening stage of the 12th season of the European Challenge Cup, the second-tier competition for European rugby union clubs. It began on 8 November 2007 when Sale Sharks hosted Montpellier and ended with the Newcastle Falcons / El Salvador game on 20 January 2008.

Twenty teams participated in this phase of the competition; they were divided into five pools of four teams each, with each team playing the others home and away. Competition points were earned using the standard bonus point system. The five pool winners and the best three runners-up advanced to the knockout stage. These teams then competed in a single-elimination tournament that ended with the final at Kingsholm Stadium in Gloucester on 25 May 2008.
