How to Join Groups on Facebook

On Mobile

Open Facebook. The Facebook mobile app icon is a white "f" on a dark-blue background. Facebook will open to your News Feed if you're already logged in. If you aren't already logged in, enter your email address (or phone number) and password, then tap Log in.

Tap the search bar. It's at the top of the screen. This will bring up your device's keyboard.

Enter a group name or keyword. Type in a group's name (or a word or phrase in which you're interested), then tap Search. This will search Facebook for accounts, pages, places, and groups that match your search.

Tap Groups. This is a tab near the top of the screen, just below the search bar. This will display any groups related to your search. You may have to swipe the row of tabs here to the left to display the Groups option.

Tap Join next to a group. The Join button is on the right side of a group's name. Tapping it will cause a "Requested" stamp to appear to the right of the group. Once you're accepted into the group by an administrator, you will be able to post in the group. If the group is public instead of closed, you'll be able to see (but not interact with) the group's posts and members.

On Desktop

Open Facebook. Go to https://www.facebook.com/. This will open your Facebook News Feed if you're logged in. If you aren't logged in, enter your email address (or phone number) and password in the top-right side of the page.

Click the search bar. This field is at the top of the Facebook page.

Enter a group name or keyword. Type in the name of a group that you want to join (or a related word or phrase), then click the magnifying glass icon on the right side of the search bar.

Click Groups. It's in the upper-right side of the search results page. This will display any groups related to your search.

Click Join next to a group. You'll see Join to the right of a group's name; clicking it will send a request to the group's moderator(s). Once you're approved to join the group, you'll be able to post in the group. If the group is public instead of closed, you'll be able to see (but not interact with) the group's posts and members.
