Facebook Messenger is a great app for chatting with your Facebook friends. And you can have one-on-one conversations or chat with a group. But there may come a time when the conversation is over. While you cannot currently leave a one-on-one conversation, you can leave a group chat.
Here’s how to leave a group conversation in Facebook Messenger on the app or website.
Leave a group chat on the Messenger mobile app
Open Facebook Messenger on your iPhone or iPad and then follow these steps to leave a group chat:
1) Tap the Chat button at the bottom of the app and select the conversation you want to leave.
2) Select the names of the people in the group at the top.
3) Scroll down and tap Leave Chat > Leave.
After leaving the Facebook group chat, other people in that group conversation will be notified that you left. Keep in mind that if you don’t want to actually leave a conversation, you can use the other two options there. You can turn off Receive Notifications or select Ignore Messages.
Leave a group chat on Messenger online

1) Navigate to the group conversation you want to leave.
