The Ulster Council announced on Monday that it would not be able to host the event in the city because of ongoing attacks from dissident republicans.
Bid organisers Comhaltas Dhoire called it an "extraordinary decision" made "against its own region," and accused the council of acting without proper information.
Now political leaders in Northern Ireland have expressed their surprise and disappointment over the decision.
Peter Robinson said: "Whatever the justification for not supporting the local bid it cannot be justified on the grounds of security issues.
"There is absolutely no reason to believe that this event would be attacked."
Martin McGuinness said: "If any of the organisers wish to meet with us in the coming days, so that we can demonstrate to them our commitment to this project and to help allay any concerns, security or otherwise they have, then we would be available for such a discussion."
The 2013 Fleadh would have been the first time the event was held in Northern Ireland, and would have coincided with Derry's year as UK City of Culture.
It is thought it could attract 300,000 people and could generate £40m to the north west.
In a letter to the council, Derry Comhaltas wrote: "We are greatly disappointed that some members of the County board and the Ulster council have introduced politics into this decision making process which directly contravenes the ethos and constitution of Comhaltas Ceoiltóirí Éireann."
The PSNI has also given its support for the bid and said the current security situation "should not prevent" the Fleadh in Derry.
A statement said: "Such an event would no doubt be enjoyed by many, enhance the city's image and bring a welcome boost to the local economy.
"It is not for police to comment on the detail of the discussion, however, we can say that any security concerns that exist in Northern Ireland should not prevent the Fleadh taking place in Derry."
Ennis and Sligo are in the running to hold the event in 2013.
