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

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.
