Rock band Oasis have officially announced two concerts at Slane Castle in County Meath on 4 and 5 September 2027, subject to licensing. The outdoor performances form part of the band's newly announced 'Live '27' tour, which will span 38 dates across Europe, North America, and the UK. Musician Richard Ashcroft has been confirmed as the special guest for all shows on the tour.

The announcement confirms weeks of speculation surrounding a potential return to the venue. Oasis previously played Slane Castle as a support act for R.E.M. in July 1995, before returning to headline the venue in June 2009. The 2009 concert marked their final show in Ireland prior to their split later that summer. The brothers subsequently reunited for their 'Live '25' tour, which included two sold-out performances at Croke Park in Dublin.

Organisers have introduced a ballot registration process for ticket purchasing to manage high demand and limit ticket touting. Fans must register on the band's official website by 4:00 pm on Thursday, 17 September 2026. Successful applicants will receive a unique access code for ticket sales running between 25 September and 27 September 2026, with no general public sale taking place outside the ballot. Standard ticket prices range from €181.25 to €501.25 including booking fees, plus a service charge of up to €10.50 per ticket.
