North American Science Fiction Convention

NASFiC, an abbreviation for North American Science Fiction Convention, is a science fiction convention scheduled in North America during years when a Worldcon is being held outside North America; NASFiCs are held only during such years. Bids for the location of a NASFiC are voted on by the membership of the Worldcon (or NASFiC if it exists), the year after a non-North-American Worldcon site has been selected. this is one year in advance of a potential NASFiC, since Worldcon sites are chosen two years in advance.

History
Activities at a NASFiC are similar to those at a Worldcon, but may differ somewhat with each convention committee. The convention may be held as an individual event or in conjunction with another convention. It generally occurs near the time of the Worldcon, but not in direct competition with it. Fifteen NASFiCs have occurred to date with the sixteenth scheduled for July 2024. The name NASFiC is owned by the World Science Fiction Society (WSFS).

The late Robert Sacks organized an attempt to separate NASFiC from the World Science Fiction Society, similar to Eurocon, but WSFS has chosen to keep control of NASFiC.
