The EDF National Trophy was a cup competition which ran from 2006 to 2009 for the 118 clubs of the Rugby Football Union from National Division One and below. Previously these teams had played in the Powergen Cup, but were excluded from that cup under a new format adopted for the 2005–06 season. The Trophy was replaced by the British and Irish Cup from the 2009–10 season. The EDF National Trophy retained the knock-out structure of the old Powergen Cup.
