Speculative poetry is a genre of poetry that focusses on fantastic, science fictional and mythological themes. It is also known as science fiction poetry or fantastic poetry. It is distinguished from other poetic genres by being categorized by its subject matter, rather than by the poetry's form. Suzette Haden Elgin defined the genre as "about a reality that is in some way different from the existing reality."
Due to the similarity of subject matter, it is often published by the same markets that publish short stories and novellas of science fiction, fantasy and horror, and many authors write both in speculative fiction and speculative poetry. The field has one major award, the Rhysling Award, given annually to a poem of more than fifty lines and to a sub-fifty lines poem by the US-based Science Fiction Poetry Association.
Much of the Romantic poetry of the 19th century used techniques seen in modern fantasy literature: retellings of classical mythology and European folklore, both to show alternative angles in the stories and to explore social issues. Many distinguished poets here were women, and many used folktales as an acceptable social camouflage with which to explore feminist concerns. One of the most celebrated of these poems, Christina Rossetti's 1862 "Goblin Market", remains a source of critical debate.
In common with the gradual recognition of science fiction and fantasy as distinct literary genres in the 1930s, science-fictional poetry began publication as a distinct genre in the pulp magazines of the United States. Fantasy-specific Weird Tales (1923–1954) and its brief compatriot Unknown (1939–43) were the only major publishers. They were succeeded by more serious venues including the US-based The Magazine of Fantasy & Science Fiction (F&SF) (1949–), the UK-based flagship of the New Wave movement New Worlds while it was under the editorship of Michael Moorcock between 1964 and 1970, and the annual reprint anthologies of F&SF and The Year's Best Science Fiction edited by Judith Merril. These anthologies drew much of their content from mainstream or literary sources.
