''The Isle of Wight Festival is legendary and we're excited to join in the long tradition of rock'n'roll history,'' he said.
''This will mark our first visit to the island and I expect it will prove to be a highlight of our tour and of 2013.''
Promoter John Giddings said: ''I can't imagine a better rock band with more hits to close our Sunday night.''
The headline act for the Saturday hasn't been announced yet.
This year, artists such as Bruce Springsteen, Pearl Jam, Tom Petty, Noel Gallagher and Jessie J were among the big-name performers.
