Who can see what you post in a Facebook group
The group’s privacy setting decides it, not your own audience setting. When you post in a group, the little audience button you see on profile posts isn’t there, because the group sets the audience for you.
| Public group | Private group | |
|---|---|---|
| Who can see your post | Anyone on or off Facebook | Members only |
| Friends who aren’t members | Can see it if they open the group, and may be shown it in their Feed | Can’t see it |
| Friends who are members | See it like any member, often in their Feed | See it like any member |
| Shows on your profile | No | No |
| Comments and reactions | Visible to anyone | Visible to members only |
Two details people miss. First, Facebook can recommend posts from public groups to people who aren’t members, so a friend can come across your post in a public group without ever visiting it. Second, if an admin switches a private group to public, Facebook keeps the old posts visible only to admins, moderators and people who were members before the switch. That rule came with Meta’s update of 3 November 2025, so what you wrote in a private group doesn’t suddenly become public.
How to check if a group is public or private
On a computer:
- Open the group.
- Look under the group’s name. It says Public group or Private group next to the member count.
- When you start a post in a public group, a globe icon also shows in the post box.
On a phone:
- Open the group in the Facebook app.
- The line under the group name shows Public or Private. Tap the group name and then About for the full description.
If the group is public and you’d rather your friends not see the post, stop here and pick one of the options below before you write anything.
How to post in a Facebook group without friends seeing: 4 ways
- Post in a private group your friends aren’t in. This is the only way that hides the post completely from them. Check the member list first: in a private group, members can see who else is there.
- Use Anonymous post. If the admins have turned on anonymous participation, your name and photo are replaced, so friends in the group see the post but not that it’s yours. Steps are just below.
- Use a nickname. Since Meta’s November 2025 update, groups with anonymous participation can also offer a nickname. Members see the nickname instead of your name.
- Post as your Page. Some groups let Pages join and post. Your Page’s name shows instead of your personal one, which keeps the post off your friends’ radar but tells everyone which business wrote it. How to post in a Facebook group as a Page covers when groups allow it.
What doesn’t work: changing your profile’s audience settings, unfriending, or restricting a friend. None of those touch group posts. In a public group, a friend who opens the group sees the post regardless.
How to post anonymously in a Facebook group
On a computer:
- Open the group.
- Click Anonymous post next to Write something.
- Read the prompt, then click Create anonymous post.
- Write the post and click Submit.
In the app:
- Open the group and tap Write something.
- Tap Anonymous post in the post screen (on some versions you switch the toggle at the top).
- Write the post and tap Submit.
If you don’t see the option, the admins haven’t enabled it. You can’t turn it on yourself. Most groups that allow it send anonymous posts to the admins first, so expect a wait like any post pending approval. And keep in mind who still knows: admins, moderators and Facebook can see the real author.
Marketplace and buy and sell groups
Sellers ask this one most, often because they don’t want friends or family to see what they’re selling.
On Marketplace there is a setting for it. When you create a listing, switch on Hide from friends before you click Publish. Your friends won’t see that listing on Marketplace.
The catch is groups. The listing form also offers to post the item in your buy and sell groups, and Hide from friends doesn’t follow it there. Anyone in those groups can see the listing, friends included. If privacy matters more than reach, leave the groups unticked, or pick groups your friends aren’t in. How to post in multiple buy and sell groups explains how the listing form handles groups.
Can friends see which groups you are in?
Separate question, separate answer. Joining a group doesn’t send your friends a notification. Whether they can find out depends on the group:
- Private group: only members can see the member list.
- Public group: the member list has traditionally been visible to anyone. For a group that switched from private to public after November 2025, only admins and moderators see the list.
- Your profile: depending on your privacy settings, the Groups section of your profile can show some public groups you belong to. Open your profile, go to More and Groups, and check what’s listed.
If you want to leave a group quietly, leaving doesn’t notify anyone either.
If you post the same thing in many groups
People who post in a lot of groups, for a business or a side hustle, run into this question at scale: the same post in twenty public groups is twenty chances for friends to see it.
MultiGroupPoster is the Chrome extension we make for posting one message to a list of groups. It posts from your own session, as you or as your Page where the group allows Pages, so the visibility rules above stay exactly the same. It doesn’t make posts anonymous or hide them from friends. What it does help with is choosing: you build group lists, so you can keep a “private groups only” list for the posts you’d rather keep away from your Feed. If you are new to group posting, start with how to post in a Facebook group, and if a group won’t let you in, why you can’t join a Facebook group lists the reasons.
FAQ
Can my friends see my posts in a Facebook group?
It depends on the group. In a public group anyone can see your post, friends included, even if they never joined. In a private group only members can see it, so friends who aren’t members can’t. Friends who are members may see your post in their Feed like any other group post.
Do Facebook group posts show up on my profile?
No. Posts you write in a group stay in the group and don’t appear on your profile’s timeline. People can still find them by opening the group, and in a public group they can show up in search and in other people’s Feeds.
How do I post in a Facebook group without my friends seeing it?
Post in a private group your friends aren’t in, or use Anonymous post if the group’s admins have turned it on. In a public group there is no setting that hides one post from your friends; the post is visible to anyone who opens the group.
Are anonymous posts in Facebook groups really anonymous?
Only to other members. Admins, moderators and Facebook can still see who wrote an anonymous post, and in most groups the post goes to the admins for review before it appears. Your friends in the group won’t see your name on it.
Are my friends notified when I post in a group?
Friends who aren’t in the group get no notification. Friends who are members get whatever their group notification settings allow, which for most people means your post can appear in their Feed or as a group notification.
Can I hide a Marketplace listing from my friends?
Yes. When you create a Marketplace listing, turn on Hide from friends before you publish. Your Facebook friends won’t see it on Marketplace, but if you also list it in buy and sell groups, members of those groups, friends included, can still see it there.
