Take That will play Dublin's 3Arena when they go on tour for the first time as a trio next year.
Gary Barlow, Mark Owen and Howard Donald will perform 24 concerts across eight arenas, kicking off at the Hydro in Glasgow on April 28.
They will appear at the 3Arena on May 8 and 9 and at the Belfast Odyssey on May 4 and 5.
The live shows come four years after the group's last record-breaking stadium tour, Progress, and marks their first without Jason Orange, who said he had quit the band in September.
Robbie Williams has also said he will not be returning for their forthcoming tour.
In a statement, Take That said: "We've always been very proud of our live shows and are very excited to be touring again next year.
"Playing live is something we love the most about what we do, and we're looking forward to putting on the most amazing show we can.
"We're really keen to get back out on the road to play some of our biggest songs from the last 20 years alongside our new ones."
Barlow tweeted: "We can't wait to get back on the road and see you all, our favourite thing to do!"
Donald added: "Hope you're all as excited as we are."
Owen said: "We're really looking forward to going back on tour and seeing you all."
Former X Factor contestant Ella Henderson will be a special guest on the tour following the success of her debut single Ghost and album Chapter One, after both reached No1 in the UK charts.
Take That's seventh studio album, III, is to be released on December 1, with the first single, These Days, due in the shops and online on November 23.
The three remaining members of the group came in for criticism earlier this year when it emerged that Barlow, Donald and Owen and manager Jonathan Wild had invested tens of millions of pounds in what have been described as tax avoidance schemes.
Tour tickets go on sale on Thursday via Ticketmaster.
