Finn Park, the home of Finn Harps, was broken into this week.
A small amount of damage was done to the pitch.
A club statement on the matter was issued on Wednesday night.
"Finn Harps FC were disappointed to find that Finn Park had been broken into on Monday night with some damage to the pitch and attempts made to gain forced entry into club shop.
"While ongoing treatment will ensure playing surface will be fixed for Friday night's derby with Derry City, it is extremely frustrating for ground staff and Harps volunteers to deal with pointless vandalism on an hugely busy week for everyone at the club.
"The matter has been reported to the Gardaí who are asking the public to forward any information which may help with their inquiries. Please contact Ballybofey Garda Station on 074 9137740 if you can help."
