Regular meetings, hosted by NA groups, are the basic unit of the NA fellowship. Meetings are held in a variety of places such as church meeting rooms, libraries, hospitals, community centers, parks, or any other place that can accommodate a meeting.

Members who attend the same meeting regularly to establish a recovery network and reliable routine understand this to be their "home group." Home-group members can participate in the group's business and play an important role in deciding how the group's meetings should be conducted.
