The artist is one of a number of celebrities to have contributed to the programme for the band's reunion gig at Manchester's Heaton Park this weekend.
Hirst, whose controversial pieces have made him Britain's richest living artist with a fortune of £215 million, applauded Ian Brown, John Squire, Reni and Mani's enormous contribution to modern culture.
Hirst wrote in the programme: "The Stone Roses are more important than Picasso."
Manchester United midfielder Ryan Giggs, his former teammate David Beckham, Noel Gallagher and Take That's Mark Owen have also shared memories of the '90s indie icons for the souvenir programme.
This weekend's concerts, which take place over three nights from Friday, have attracted some controversy, with photographers boycotting the event over a disagreement about copyright.
