How do I delete a friend request?
A friend request that you've received is a pending request until you accept or delete it. If you delete a friend request, the person who sent you the request won't be notified. You can prevent that person from sending you another friend request by blocking them.
To delete a friend request:
- Go to facebook.com/find-friends
 - Click Delete Request
 
Note: if you reach 1,000 pending friend requests, you won't get any new requests.
How do I remove or cancel a friend request I sent to someone?

- Click 
 at the top of any Facebook page - Click Find Friends

 - Hover over 
Friend Request Sent next to the request you'd like to cancel
