Despite industry rumours that the French duo would be present at Ireland's leftfield boutique festival Electric Picnic, Daft Punk will be entertaining Oxegen-goers at Punchestown Racecourse in Co. Kildare, which takes place on July 7 and 8.
Also newly announced for the bill are Tori Amos, CSS and Kings Of Leon.
They join a line-up which includes headliners Snow Patrol and Muse, plus Arcade Fire, Director, Razorlight, Bloc Party, Amy Winehouse and Interpol.
Tickets for the two-day fest go on sale on March 3.
