Corflu is a science fiction fanzine convention held each spring in North America (and three times in Britain).
It is named after a slang term for the "correction fluid" used in mimeograph printing, a common way to produce fanzines before the arrival of low-cost photocopying and online fanzines.
Each Corflu is organized by a different regional group, selected at the previous year's gathering.
Corflu is a small, informal convention with a single track of programming.
Corflu's traditions include choosing the Guest of Honor randomly from the attendees and electing past presidents of the Fan Writers of America (which never has a current president).
