Saving you from the post-Christmas blues, the promotion will run from 26 December to 6 January and offer up a free download every day.
There will be a mixture of music, videos, apps, TV shows and films over the 12 days, from "some of the biggest star performers on iTunes".
The downloads will only be available for 24 hours, so remember to check back every day to see what's up for grabs.
To help, you can sign up for email alerts, or receive alerts over Facebook by becoming a fan of iTunes (UK) on the social networking site.
Head over to the 12 Days of Christmas site for more deets, and let us know below what you fancy Apple giving you for free this Christmas.
