As US space agency Nasa says, the full moon will appear brightest at 11:11pm GMT, but it'll be full throughout the day - so if you woke up early to see if Santa had been, you may have caught a glimpse of it.
This full moon is the last of the year, and is nicknamed the 'Full Cold Moon', since it occurs at the beginning of winter.
According to NASA, the Full Cold Moon will still be full the next night on December 25.
