The final of the inaugural European Rugby Champions Cup will be hosted by Twickenham next year.
The tournament organisers had offered the nations with clubs that compete in the Aviva Premiership, the Guinness PRO12 and the Top 14 the option to bid for the right to host the showpiece event.
Following that process, the Rugby Football Union has been awarded the encounter, which will be played on May 2.
"In the inaugural season of the tournaments, the board of EPCR took the view that fairest and the most commercially-sound approach was to award the finals based on a competitive tender process. The RFU's bid was extremely strong and the fact that we are going to London for the 2015 finals is hugely positive for European club rugby," said EPCR director Bruce Craig.
"Twickenham Stadium and the Twickenham Stoop tick every box for fans wishing to attend both the Champions Cup and Challenge Cup finals next May and with both venues steeped in rugby history, we are certain that the weekend will be an unforgettable experience."
The final of the Heineken Cup, which has been replaced by the European Rugby Champions Cup, would have been held in Milan.
