There are 10 lots in the auction, which include five pairs of Glastonbury 2016 tickets and several on-site experiences - the proceeds of which will go straight to Oxfam's Refugee Crisis Emergency Appeal.
Lovers of the Somerset countryside will even have the opportunity to see Worthy Farm free of festival-goers by bidding for a Land Rover tour with founder Michael Eavis and the use of a Glastonbury festival meeting room.
Co-organiser Emily Eavis said: "The plight of refugees who have left their homes due to fear and aggression has moved everyone in the Glastonbury Festival team and we want to do something to help.

"We hope this auction will raise many thousands of pounds so that Oxfam, which has been a trusted partner of Glastonbury for many years, can deliver the support these people so desperately need."
After this year's festival, more than 500 pairs of discarded wellington boots, 2,000 unused ponchos and some first aid kits were donated to migrants in the French port town of Calais.
The online auction, on the Oxfam Shop on eBay, will run until Tuesday October 13.
