Belfast has been confirmed as the venue for Fleadh Cheoil na hÉireann 2026.
It follows a bid by Belfast City Council and Ards Comhaltas to bring the event to the city.
It will be the first time the Fleadh is held in Belfast and only the second time it has come north in 75 years.
Hundreds of thousands of people are expected to attend bringing a huge economic boost to the city.
Around 650,000 people are expected to attended bringing spending power of at least €70m.
It will run from 2 August to 9 August 2026.
Belfast Lord Mayor Micky Murray said the city would be a wonderful venue.
"I have no doubt that the Fleadh in Belfast will be something unique.
"It will be a truly inclusive festival that will allow all our citizens - and visitors from near and far - to celebrate together.
Dr Labhrás Ó Murchú, director general of Comhaltas, thanked the city council and Ards Comhaltas for their work in the successful bid.
"It'll be just the second in its 75-year history that the Comhaltas Fleadh Cheoil will be held north of the border.
"The legacy of the 2014 Comhaltas Fleadh in Derry City is still widely spoken about, making this a fantastic opportunity for Belfast to create its own legacy."
Some 2,000 volunteers will be needed to help run the event.
A huge cheer greeted the confirmation at an event in Belfast City Hall this afternoon.
