Noel Gallagher has confirmed plans for Oasis to play two super gigs next year
Oasis will play a series of outdoor gigs in the UK and Ireland next summer.
The band announced the shows, which include dates at London Wembley Stadium and Manchester Heaton Park, at a press conference on Thursday.
Support on the tour, which also visits Sunderland, Edinburgh and Dublin's Slane Castle, will come from Kasabian and The Enemy.
Noel Gallagher said: "I think these gigs are easily going to be the biggest gigs of next year if not the decade."
He added: "These are the concerts that will go down in people's memories and this is where people will meet future wives. We're bang up for it."
The 2009 tour visits:
- Manchester Heaton Park - June 6-7
- Sunderland Stadium of Light - 10
- Cardiff Millennium Stadium - 12
- Edinburgh Murrayfield Stadium - 17
- Slane Castle - 20
- London Wembley Stadium - July 11-12
Tickets go on sale at 10am on October 24.
Speaking about the bands who will support Oasis, Noel explained: "We always said when we were doing the big super gigs again we would give Kasabian first option.
"As for The Enemy I've liked them since their first ever single. So with the three bands on one night if I was 16 or 17 I'd be here.
"To be honest I'm actually really made up with the bill and when you see it in front of you, you just think, 'What a night out!'. I'm just glad I'll be able to get tickets."
Previously, Noel Gallagher told the BBC Oasis had a giant show planned in their home town.
But the band gave no indication of a wider UK and Irish tour until this afternoon.
The show at Slane Castle on 20 June, 2009, will be the first time they have returned to the venue since they backed REM there 13 years ago.
Oasis are also set to headline the BBC Electric Proms at the London Roundhouse on 26 October with the Crouch End Festival Chorus.
The band went to Number One this week with their seventh album Dig Out Your Soul.
