The Millennium Stadium will host the 2014 Heineken Cup and the Cardiff Arms Park will host the Amlin Cup final.
ERC’s 2014 finals are set to go ahead in the Welsh capital with the Amlin Challenge Cup final played at the Cardiff Arms Park on Friday, 23 May and the 19th Heineken Cup showpiece event staged the following day at the 74,500-capacity Millennium Stadium.
The Welsh Rugby Union, with the support of the Welsh Assembly Government and local partners, were awarded the ERC finals following a competitive bid process.
The city successfully staged the two finals in 2011 with the weekend of matches generating a direct financial dividend of £24m for Cardiff.
Four Heineken Cup finals have been played to date at the Millennium Stadium, with the most recent decider two years ago producing a classic European contest when Leinster defeated Northampton Saints with a dramatic second-half comeback.
Speaking at the announcement in Cardiff, ERC chief executive Derek McGrath, said: "Cardiff has been the setting for some of the great finals in the past and in many ways, European club rugby is returning home.
"I have no doubt that the 2014 weekend at the Cardiff Arms Park and the Millennium Stadium will be yet another celebration of all that is good about European club rugby."
Tickets for the finals will go on sale in early September and following the huge demand for last season's innovative offering which included tickets for both matches and passes to local tourist attractions, ERC is working with its local partners in Cardiff to develop a similar two-final European club rugby festival package for 2014.
