Bouchercons, the Anthony Boucher Memorial World Mystery conventions, are annual meetings of creators and fans of mystery and detective fiction.

The Bouchercon is named in honor of critic/writer/editor Anthony Boucher, the principal pseudonym used by William Anthony Parker White, SF editor and mystery writer.

Bouchercon is very much a spinoff of SF fandom, with con-running fans such as Bruce Pelz, Len Moffatt, and his wife June Moffatt being its founders.
