Readercon is an annual science fiction convention, typically held every July in the Boston, Massachusetts area, currently taking place in Quincy, Massachusetts.

It was founded by Bob Colby and Eric Van in 1987[1] with the goal of focusing almost exclusively on science fiction, fantasy, slipstream and speculative fiction in the written form.

On the rare occasion that there is a discussion held about non-written science fiction, it will have a tongue-in-cheek title such as "Our biannual media panel".

Past guests of honor have included authors such as Greer Gilman, Gene Wolfe, Octavia E. Butler, Samuel R. Delany, Karen Joy Fowler, Brian Aldiss, Nalo Hopkinson, Joe Haldeman, Caitlín R. Kiernan, Peter Straub, and China Miéville, and editors such as Ellen Datlow and David G. Hartwell.

[4] From 2005 to 2011, Readercon was the official venue for presentation of the Rhysling Award.
