The International Association for the Fantastic in the Arts (IAFA), founded in 1982, is a nonprofit association of scholars, writers, and publishers of science fiction, fantasy, and horror in literature, film, and the other arts. Its purpose is to promote and recognize achievement in the study of the fantastic.

Its principle activities are (1) the organization of the International Conference on the Fantastic in the Arts (ICFA), which was first held in 1980, (2) the organization of the Virtual International Conference on the Fantastic in the Arts (VICFA) held first in 2021, (3) the publication of the Journal of the Fantastic in the Arts (JFA), a peer-reviewed journal for scholarship within the field of the fantastic which has been published regularly since 1990, and (4) the production of a news blog and other social media that publish information of interest to the membership.

Membership in the IAFA is open, but almost all members are scholars, teachers, and graduate students in the field of Science fiction studies, Fantasy literature, Horror literature, or are authors.
