Northern Kin Festival was due to take place at Thornley Hall farm, in County Durham, at the beginning of August.
Organiser Wannasee Ltd had previously said discussions were underway to preserve the festival after 10 of its other events, including Stone Valley North and Kubix, were cancelled at the end of May.
But a social media post on Wednesday confirmed Northern Kin would not be going ahead, despite the team having worked “around the clock” to find a way to run it.
“We are heartbroken to confirm that Northern Kin will not be going ahead this year,” the post said.
