There are far too many conventions to list! I recommend exploring the first link below - Convention Scene - to get a sense of where and when conferences are being held. Also check out the links to conventions on our Comic Book and Graphic Novels guide - there is obviously overlap!
Convention Scene
- Provides a schedule of upcoming events for world-wide science fiction and fantasy conventions.
Worldcon: The World Science Fiction Convention
- “Worldcon is the annual convention of the World Science Fiction Society (WSFS). It was first held in 1939 and, after a hiatus during WWII, has been held continuously since 1946.”
World Fantasy Convention
- “The first World Fantasy Convention (WFC) was held in 1975 in Providence, Rhode Island and it has continued as an annual gathering and reunion of professionals, collectors, and others interested in the field of light and dark fantasy art and literature. The convention is generally held on one of the two weekends bracketing Halloween, with some light early-bird programming usually beginning Thursday evening and the convention generally concluding Sunday afternoon, usually shortly after the World Fantasy Award Banquet. The awards banquet is a culminating highlight of the convention, offering awards ranging from lifetime achievement, to various aspects of art and literature. Additional highlights include an autograph reception, and often some sort of reception honoring the arts. Individual conventions often use programming and special events to highlight the themes of the convention and local flavor.”
