He's making a list, and checking it twice — and pretty soon Santa Claus will be loading up his sleigh and heading off to deliver presents around the world.
And you can add even more festive excitement to Christmas Eve by tracking his journey with the NORAD Santa Tracker!
The service offers a live 'Santa Cam' and tallies the number of gifts delivered as Christmas Eve progresses.

The North American Aerospace Defense Command (or NORAD) began tracking the man in red after a 1955 advert encouraged children to phone Santa - but gave the wrong number.
When he realised what had happened, Colonel Harry Shoup - who came to be known as the “Santa Colonel” - quickly told his staff to answer the calls with an update on Father Christmas's current position.
And the practice has continued ever since, developing into a tradition where volunteers staff call centres on Christmas Eve and field around 70,000 phone calls each year from 200 countries.
This year, the NORAD tracker isn't the only bit of Christmas magic to ramp up the festive excitement.
If you cast your eyes to the night skies at the right time today, you should be able to spot Santa in his sleigh flying over Huddersfield!
OK, so you'll actually be able to see the International Space Station. But many parents are using the well-timed flyover to add some extra magic to Christmas Eve.
