The event in Pilton was set to welcome superstars Paul McCartney, Taylor Swift and Kendrick Lamar as headliners for its 50th anniversary celebrations in June.
Posting on Twitter the Eavis', who run the festival, said it was "not a course of action we hoped to take for our 50th anniversary event."
But they added, because of the current situation: "We are no longer able to spend the next three months with thousands of crew on the farm, helping us with the enormous job of building the infrastructure and attractions needed to welcome more than 200,000 people to a temporary city in the fields."
