Duckon is an annual science fiction convention held every June in the Chicago area. The name is a reflection of the convention organizer's suburban roots, a shortening of DUpage County KONvention (DuPage County being located just west of Chicago).
Duckon is also notable because it is a fundraiser for Super-Con-Duck-Tivity, an organization that is known worldwide for its Golden Duck Awards for excellence in children's science fiction literature.
The first Duckon was held in 1991. The first three Duckons were chaired by Candis King, wife of Robert King. Duckon 3 was the first year that the convention had a furry track of programming; that furry track grew over the years and eventually split off in 2000 to become its own convention: Midwest FurFest. Since 2003, various people including Chouette, Barbarian, and Robert King have put together a small slate of of furry-related panels at Duckon each year.
