Science fiction fandom is the participatory culture built by readers, viewers, writers, editors, artists, collectors, convention organizers, fanzine editors, archivists, and friends around science fiction and fantasy. It is not just an audience. It is a community that makes things.

A Simple Definition
Science fiction fandom is what happens when people who love speculative stories start writing back, meeting each other, publishing, arguing, organizing, collecting, singing, costuming, voting, archiving, and building institutions. The books and films matter, but fandom is the social world that grows around them.
Classic Forms of Fan Activity
- Fanzines: fan-made magazines that carried essays, art, reports, jokes, reviews, and letters.
- Conventions: gatherings such as Worldcon, regional conventions, relaxacons, and club events.
- Clubs: local or correspondence-based groups that helped fans find one another.
- Fanac: the practical work of doing fandom, from editing to volunteering.
- Fanspeak: the slang, acronyms, and inside vocabulary of fan culture.
Why Fandom Became Historically Important
Science fiction fandom became important because it created durable institutions before the genre itself was fully respectable. Fans organized conventions, built archives, debated awards, preserved magazines, launched professional careers, and documented their own culture. Many writers and editors came through fandom before or alongside professional work.
