Santa has left the North Pole and is already on his way.
He has loaded up his sleigh with presents and will be visiting a number of countries before he gets to Ireland.
You can now see where he is: TRACK SANTA HERE
Santa's message to children in Donegal is: "Go to bed early, snuggle up and keep warm and have a great night's sleep. I have lots of surprises for you in the morning."
Because the world is divided up into different time zones, it means that children in places like Australia and New Zealand get their presents from Santa before children in Ireland.
This special Track Santa website has been set up by the North American Aerospace Defence Command (NORAD), and uses satellites to track Santa's journey all around the world.
It has just issued this special video about how it is tracking Santa.
The website also has plenty of information and even games.
