# Delete a local group
This API lets a server admin delete a local group. Doing so will kick all
users out of the group so that their clients will correctly handle the group
being deleted.
The API is:
```
POST /_matrix/client/r0/admin/delete_group/<group_id>
```
including an `access_token` of a server admin.
