Westlife will play Cork's Páirc Uí Chaoimh for the first time on August 28, 2020.
The foursome delighted fans with the news that they will play "a major concert" in the 45,000-seater GAA grounds next year during a press conference at the stadium on Monday morning.
While lead singer Shane Filan insisted that the concert at Páirc Uí Chaoimh next year will be Ireland's only "bespoke concert" in 2020, the band held out the prospect of playing further gigs in Cork if the August 28 gig sells out.
All four of the band members admitted that being privileged to play sell-out concerts for their Irish fans is like "being able to relive your youth."
"It is absolutely fantastic to be playing for our Irish fans. It really is like getting to relive our youth," Shane said.
The four-piece, who are currently promoting their eleventh studio album, Spectrum, set for release on November 8, said they are "over the moon" to be playing in the fourth-largest GAA stadium in Ireland next summer.
Taking to social media, the band posted: "We're over the moon to announce we’re going to be playing Páirc Uí Chaoimh in Cork for the first time ever next year!
"We can’t wait to bring this show to Ireland which will be more spectacular than anything we’ve ever done before🌟 Tickets go on sale Friday 20th September at 9am."
The group recently completed their comeback Twenty tour which opened in Belfast on May 22, along with playing two sold-out gigs at Dublin's Croke Park.
Westlife previously announced they will play their first Wembley gig on August 22 next year, with tickets going on sale on September 20.
