Boskone is an annual science fiction convention run by the New England Science Fiction Association in Boston, Massachusetts. In the words of the convention organizers, "Boskone is a regional Science Fiction convention focusing on literature, art, music, and gaming (with just a dash of whimsy)".
It is held every February, in Boston. The name is a reference to the classic Lensman series by E. E. Smith, in which "Boskone" is a council of villains, and also a name for their civilization. Boskone typically features a guest of honor, an official artist, a science speaker, a featured filker, and a special guest.
Guests for 2019 include Elizabeth Hand, Christopher Golden, Jim Burns, Cindy Pon, and Vandana Singh.
