Challenge was a small press poetry periodical edited by Lilith Lorraine (Mary M. Wright) and published by Avalon Arts Academy. Assistant editors were Stanton A. Coblentz and Evelyn Thorne.
Lilith Lorraine began publishing in the 1940s with Different, a periodical mainly devoted to fantastic fiction that also included science fiction. She began to also publish Challenge in the 1950s in Rogers, Arkansas, U.S.A. The subtitle for the publication was "The Poetry of the Atomic Age", and the focus was entirely on science fiction and weird fantasy poetry. Challenge is credited as the first poetry periodical devoted to a specific genre. Issue three was released in Winter 1950. Issue 4 came out in Spring 1951. It was then absorbed into Lorraine's existing publication Different.
