Powys County Council in Wales plans to cut nearly £63,000 of arts funding.
The same amount has already been cut from this year's budget and local venues warn they can't sustain a further reduction.
Hafren Theatre and Wyeside Arts Centre are among those most at risk.
But councillors say there are many more local arts organisations – up to 143, it is estimated – that it doesn't currently support at all.
The cuts had been agreed pre-Covid: "“There are other sources of funding especially during Covid that arts organisations have been able to apply for," Culture and Leisure Portfolio Holder Councillor Rachel Powell said.
