Fáilte Ireland says over 100,000 people attended last year's festival of events, making it clear that events this year would not be in line with the Government's public health guidelines.
The organisation says it would not be appropriate to encourage people to congregate in those sorts of numbers.
Orla Carroll, Director of product development with Failte Ireland says there was simply no way the celebrations could go ahead as originally planned.
"This isn't what we all would like to happen, but it's health first and that's what we need to focus on.
"Last year, after the fireworks alone, we had over 80,000 people on the streets and now we are looking at gatherings of 15 people, so it's not possible unfortunately.
"But that doesn't mean there isn't alternatives and we are working hard to see what we can do to bring people into the city in a controlled environment.
Dublin's Lord Mayor, Green Party Councillor Hazel Chu says the Dublin City Council is working to come up with alternative celebrations for the festive season.
"It will be a different kind of Christmas. We'll be having the 12 days of Christmas in the Mansion House, a lot of which will be live streamed and we're in the process of thinking of ideas right now."
