The Killers and Franz Ferdinand are the latest names added to the Pinkpop bill.
Both bands were 'Golden Tips', a scheme launched by the event's organisers, which allowed festival-goers to nominate who they wanted to play the festival in 2009.
They join the likes of Bruce Springsteen And The E-Street Band, Depeche Mode, The Kooks and Placebo.
Pinkpop Festival 2009 will take place at Megaland in Holland from 30 May to 1 June, but tickets are not on sale until 7 March.
Some 60,000 fans are expected to attend.
