The STARFLEET International Conference is the organization’s largest annual event  and in person business meeting where members of STARFLEET: The International Star Trek Fan Association, Inc. gather together to participate in meetings, information sessions/panels, a formal banquet, an awards ceremony, meet the organization’s leadership, enjoy various forms of entertainment, as well as other events.

The International Conference is also the annual gathering of some of the organization’s affiliate groups such as the STARFLEET Marine Corps (SFMC) who host a muster for all Marines in the Fleet with it’s own events, banquet, and awards ceremony. The Marines also participate in the opening and closing ceremonies of the IC as well as the Final Mission Ceremony which is dedicated to all the members  of the organization that have passed during the year.

Starting in 2020 due to the world wide pandemic, the International Conference was moved into a virtual format.  2021-2023 was continued in this format, allowing anyone who registered that were paid SFI members to go to the event.  As of 2024, the International Conference has went back to in person with a virtual component, thus serving the rather wide spread membership of STARFLEET, International.
