It will be the first time that horror fans in the area won't be able to attend since 2011.
It is a sad day for fans of being scared who happen to live in the south of the country.
Despite being a huge attraction for the last seven years, the Nightmare Realm will not be returning to Cork this year.
Karl O’Connor, the director of The Nightmare Realm, told the
Evening Echo the following: "After seven years in Cork, unfortunately, we have been unable to find a suitable venue for 2018.
"We are heartbroken not to be there this year, as we feel Cork is our spiritual home, and it was the people here who made the event what it is. We have had so much fun over the years doing what we do, making new friends, and building a haunt family of amazing supporters."
The Nightmare Realm's previous location is now being turned into the Navigation Square office block in the city centre.
In some good news, the Dublin branch of the interactive horror experience will be going ahead at the RDS from Friday 5 October to Saturday 3 November, and there will actually be a Nightmare Coaches set-up for anyone who wants to head up to get their scary fix.
The Nightmare Coach is €30 on Thursday 18 October and €35 on Saturday 20 October, and the price includes a return bus transfer, a horror movie on board, a meet and greet with one of the creatures and a fast pass ticket.
