The Socialite Network: UK's Queen joins Facebook
The 84-year-old British monarch will be featured in videos, photos and news updates on the site, her office said on Sunday.
Users will be able send messages to Buckingham Palace, and leave comments on the Queen's pages.
Britain's court circular, the official daily record of the royal family's engagements, will also be featured on the site. The daily circular - which lists the previous day's diary appointments - was created by George III in 1803 after he became frustrated at inaccurate newspaper reports.
Britain's royal family already has an account on the Flickr photography website, joined Twitter in 2009 and set up a video channel on YouTube in 2007.
