Westlife 25: The Anniversary World Tour

Westlife are back at The O2 Belfast (SSE Arena Belfast) for seven shows, running from Tuesday 27 October to Friday 6 November 2026. It's part of their 25th anniversary celebrations, and the run extends the venue's record for the most shows ever performed by a single artist — a milestone no other act has come close to matching. Ana Sky supports on the nights.

Formed in Sligo in 1998, the band built their following on a string of ballads and club-ready hits. Over the last 25 years they've become one of the most successful pop acts of all time: more than 3 billion streams globally, 36 No.1 albums worldwide, 14 UK No.1 singles, over 55 million records sold and more than 6 million concert tickets, with The Wild Dreams Tour alone selling over 1.2 million. Since their 2019 reunion they've played more than 200 shows across 30 countries and remain the UK and Ireland's top-selling album group of the 21st century.

The set leans on the greatest hits, including 'Swear It Again', 'Flying Without Wings' and 'You Raise Me Up'. With seven dates to choose from, you've got a fair bit of leeway on when to catch them. Doors open at 6:30pm, and the venue is at 2 Queens Quay, Belfast, BT39QQ.
