The legendary pop-rock act's forthcoming 'Fleetwood Mac Unleashed: Hits Tour 2009' will call at the Somerset festival in June, according to eFestivals.
Stevie Nicks and Mick Fleetwood's band are expected to play on the Saturday, underneath confirmed headliner Bruce Springsteen.
The band's tour will apparently promote their greatest hits and a re-release of the classic album Rumours rather than new material.
Neil Young, Bruce Springsteen and Blur are expected to headline this year's Glastonbury. Kaiser Chiefs, Lily Allen, The Specials, Franz Ferdinand, Madness, The Ting Tings, Lightning Seeds and Rolf Harris have also been linked to the five-day festival.
