2011–12 European Challenge Cup
The 2011–12 Amlin Challenge Cup was the 16th season of the European Challenge Cup, Europe's second-tier club rugby union competition. The tournament began with two matches on 10 November 2011 and ended with the final on 18 May 2012 at the Twickenham Stoop in London. A total of 23 teams from six countries participated—20 in the pool stage, plus three teams parachuting into the knockout stages from the Heineken Cup. In an all-French final, Biarritz claimed their first Challenge Cup, defeating Toulon 21–18. The Basque club claimed a place in the 2012–13 Heineken Cup, which will be their 13th consecutive appearance in Europe's top club competition. The defending Challenge Cup champions, England's Harlequins, did not initially have a chance to defend their crown because they had earned an automatic berth in the Heineken Cup. However, Quins parachuted into the knockout stage of this season's Challenge Cup, losing to Toulon in the quarter-finals. All four semi-finalists were from France, equalling the achievement of 1996–97 and 1998–99. Teams Teams that parachuted in from the Heineken Cup are in italics.
