Windycon is a science fiction convention currently held in Lombard, Illinois, on the weekend closest to Veterans Day.
Windycon was founded in 1973 in Chicago and has been held annually ever since either in Chicago or a Chicago suburb. It is a general interest convention. The convention is run by the parent organization ISFiC.
Windycon was originally founded in order to raise the profile of fandom in Chicago in preparation for a Worldcon bid. In 1982, Chicon IV was the result. From its small beginnings, Windycon has grown to have an annual membership hovering around 1300. It is the largest of the three fan-run Chicago conventions.
Annually since 1986, ISFiC has hosted a writers contest, open to unpublished authors. The contest is judged by professional authors and editors. Separately, Windycon has hosted a Writer's Workshop under the coordination of Richard Chwedyk since 2000.
Beginning in 2004, ISFiC Press has published books by Windycon's guests of honor, which go on sale during the convention and are available through normal bookselling channels.
In addition to traditional con activities, Windycon has also run a series of on-line chats during the con, hosting by Cybling.
