How to Undo a Friend Request on Facebook

Have you accidentally friend requested someone, or otherwise just decided you want to revert adding him or her to your Facebook friends list? There is no explicit option to take back the addition, but it is possible — you have to block him or her, then unblock (if you wish to do so). This is how it’s done through the new Facebook layout.

To block a person, hover over the Settings link (toward the top-right corner to the left of the search box), and go to Privacy Settings. From there, under Block List you should see a search box. Search the person’s name, and you can find and block them in the search results that follow. To unblock them, click the (remove) link by their name on the Privacy Settings page. The pending friend request confirmation should now be purged.
