The community centre in Forkhill was vandalised on Wednesday.
The incident at the centre on the Bog Road happened during the day.
Two glass panels in the front door were smashed with large rocks.
Sinn Féin councillor Mickey Larkin said: “This is essentially an attack on the community of Forkhill. If anyone has information relating to this incident I would encourage them to bring it forward.
“The cost of the repairs will in the end be borne by the ratepayer.”
