You can delete Facebook contacts in three ways, depending on what you want to happen
Removing someone from your Facebook friends list does not delete their account or prevent them from seeing your public posts. It straightforward ends the friendship connection — they can still message you, see what you share publicly, and send you a new friend request later. If you want to block someone instead (so they cannot message you or see your profile at all), that is a separate, stronger action. Most people who want to "delete" a contact actually just want to unfriend them, which takes seconds.
The three main options are unfriending (removes them from your list but they can still see your public content), blocking (prevents them from contacting you or viewing your profile), and restricting (lets them stay on your list but limits what they see). Which one you choose depends on whether you want to stay loosely connected or cut contact entirely.
Key Takeaways
- Unfriending someone removes them from your friends list but does not prevent them from seeing your public posts or sending you a message request.
- Blocking someone prevents them from messaging you, viewing your profile, or finding you in search — it is the strongest option if you want no contact.
- Restricting a friend keeps them on your list but hides your posts from them unless you specifically share with them.
- You can unfriend or block someone from their profile, from your friends list, or from a conversation — the result is the same regardless of where you start.
- If you unfriend someone by mistake, you can send them a new friend request, but they will see that you removed them if they check their friends list.
How to unfriend someone on Facebook
Unfriending is the simplest removal option and takes one click. Go to the person's Facebook profile, look for the "Friends" button (it usually appears near the top of their profile next to a message button), click it, and select "Unfriend" from the menu that appears. On mobile, tap the three dots next to their name instead, then tap "Unfriend".
You can also unfriend someone from your own friends list without visiting their profile. Open your profile, click "Friends" to see your full list, find the person you want to remove, hover over their name, click the three dots that appear, and select "Unfriend". On mobile, swipe left on their name in your friends list and tap the trash icon.
After you unfriend someone, they will not receive a notification that you removed them — but they can figure it out by checking whether you still appear in their friends list. Your past messages with them stay in your inbox, and they can still see anything you posted publicly before the unfriend and anything you post publicly after.
How to block someone on Facebook
Blocking is stronger than unfriending. When you block someone, they cannot see your profile, message you, find you in search, or see your posts even if they are public. They also cannot add you as a friend again unless you unblock them first. Use blocking when you want no contact with someone and do not want them to be able to find you on the platform.
To block someone, go to their profile, click the three dots in the top right corner, and select "Block". On mobile, tap the three dots and choose "Block". You can also block someone from your settings: go to Settings, click "Blocking" on the left side, type their name in the "Block users" box, and click "Block" next to their name.
When you block someone, Facebook does not tell them they are blocked — but they may figure it out if they try to visit your profile and cannot find it, or if they search for you and you do not appear. If you change your mind, you can unblock them from the same Blocking settings page, and they will be able to add you as a friend again.
How to restrict someone without unfriending them
Restricting is a middle ground between unfriending and staying fully connected. When you restrict someone, they stay on your friends list, but they cannot see when you are online, they cannot see your posts unless you specifically share with them, and they cannot see comments you make on other people's posts. Restrict someone when you want to keep the friendship but limit what they see about you.
To restrict someone, go to their profile, click the three dots, and select "Restrict". On mobile, tap the three dots and choose "Restrict". You can also restrict someone from your friends list: open your friends list, find their name, click the three dots next to it, and select "Restrict".
The person you restrict will not be notified, but they may notice over time that they see fewer of your posts. You can unrestrict them the same way — go back to their profile or your friends list and select "Unrestrict".
Removing contacts from Facebook Messenger
If you want to remove someone from your Messenger contacts without unfriending them on Facebook, you can delete the conversation. Open Messenger, find the conversation with the person, swipe left on it (mobile) or right-click it (desktop), and select "Delete". This removes the conversation from your inbox but does not unfriend them or block them — they can still message you, and you can still message them.
If you want to prevent someone from messaging you without blocking them entirely, you can ignore their messages instead. In Messenger, swipe left on their conversation (mobile) or click the three dots (desktop) and select "Ignore". Their messages will go to a separate "Message Requests" folder, and they will not know you ignored them. You can check that folder anytime and respond if you change your mind.
What happens to your data when you unfriend or block someone
Unfriending or blocking someone does not delete your past conversations with them. The messages stay in your inbox, and you can read them anytime. However, if you blocked someone, they cannot see those old messages — the conversation is hidden from their side. If you unfriended someone, they can still see old messages you sent them in Messenger.
Photos and posts you shared with them before the unfriend or block remain on Facebook, but they may not be able to see them depending on your privacy settings. If you posted something publicly, they can still see it even after you unfriend them. If you posted something only to friends, they cannot see it after you unfriend them.
If you want to remove a specific post or photo from someone's view, you need to delete the post itself or change who can see it — unfriending or blocking does not retroactively hide old content. You can edit the privacy settings on old posts by clicking the three dots on the post and selecting "Edit privacy".
Removing multiple contacts at once
Facebook does not have a built-in tool to unfriend multiple people at the same time. You have to remove them one by one. However, there are third-party browser extensions that claim to let you bulk-unfriend, though Facebook's terms of service discourage using them, and they may not work reliably after Facebook updates its interface.
The fastest manual way is to open your friends list, use the search box at the top to find the people you want to remove, and unfriend them in order. On mobile, this takes longer because you have to go to each person's profile individually, so consider doing bulk removals on a computer if you have many people to unfriend.
Frequently Asked Questions
Can someone tell if I unfriended them?
Facebook does not send a notification, but they can figure it out by checking whether you still appear in their friends list. If they visit your profile and the "Add Friend" button appears instead of "Friends", they will know you unfriended them. They cannot see exactly when you did it.
What is the difference between unfriending and blocking?
Unfriending removes them from your friends list but they can still see your public posts and message you. Blocking prevents them from seeing your profile, messaging you, or finding you in search. Blocking is stronger and should be used when you want no contact.
If I unfriend someone, can they still see my old posts?
They can see posts you made public before and after the unfriend. They cannot see posts you made only for friends. If you want to hide old posts from them, you need to change the privacy setting on each post individually or delete them.
Can I unfriend someone and then add them back later?
Yes. After you unfriend someone, you can send them a new friend request anytime. They will see that you removed them if they check their friends list, but they can accept the new request if they want to reconnect.
Does unfriending someone delete our messages?
No. Your message history stays in your inbox after you unfriend someone. You can read old messages anytime, and they can still read messages you sent them in their inbox. If you blocked them instead, they cannot see those messages.
