Môn Mam Cymru will welcome an extended Eisteddfod Genedlaethol yr Urdd next year.
Anglesey Council has welcomed Urdd Gobaith Cymru's plans to extend the event to seven days from 2026.
Organisers say it's in response to an increase in the number of entries as well as demand for more competitions.
The festival - the biggest of its kind in Europe - welcomes around 100,000 visitors every year and was last held on Anglesey back in 2004.
Council leader Gary Pritchard said: "Welcoming this unique festival – that will now last seven days when it comes to the site in Mona – will be a significant boost to the Welsh language, our young people and the economy."
"As a county council and island, we are truly looking forward to welcoming Eisteddfod Genedlaethol yr Urdd in a year's time."
"There is nowhere better than Anglesey to stage this Welsh event for the young people of Wales, and following today's announcement, we will have a full week of competing."
"I'd like to thank Urdd Ynys Môn's executive committee and all volunteers for working tirelessly to ensure that Anglesey will, once again, be an exemplary home for this special festival in 2026."
"I look forward to seeing children, young people and families from all across the country visiting Anglesey."
Competition will begin on Saturday 23rd May and will run until Friday 30th May, with Gŵyl Triban moving to the opening weekend.
Anglesey Council CEO Dylan J Williams said: "There is significant local enthusiasm, and people are eager to welcome this unique youth festival to the island. It's a great opportunity for us to show Anglesey at its best."
"We will continue to work with the Urdd and local committee, with the aim of welcoming the Eisteddfod, and people from across Wales, here in 2026."
