Extrapolation is an academic journal covering speculative fiction, established in 1959.

Extrapolation was established in 1959 by Thomas D. Clareson and was published at the College of Wooster.

A decade later, Clareson stepped down as editor-in-chief and was succeeded by Donald M. Hassler of the KSU English Department.

[1] Extrapolation covers all areas of speculative culture, including print, film, television, comic books, and video games, and particularly encourages papers which consider popular texts within their larger cultural context.

It is interested in promoting dialogue among scholars working within a number of traditions and in encouraging the serious study of popular culture.
