Various embodiments of the present disclosure provide apparatuses, systems, and computer program products for group-based communication channel organization. In this regard, embodiments described herein are configured to enable group-based communication interfaces rendered with group-based communication channels organized into specific organized channel sets. A plurality of organized channel sets may be reorganized, and/or the associated channel set for each organized channel set may be reorganized. In one example embodiment, an apparatus is configured to receive an interface rendering request associated with an authenticated user account and a group-based communication interface, identify at least one organized channel set associated with the authenticated user account, and cause rendering of the group-based communication interface comprising an organized channel set interface element set, each organized channel set interface element in the organized channel set interface element set associated with one of the at least one organized channel set.
