Speculative fiction is generally defined as a genre of fiction where the setting is not in the world as we know it because of supernatural, fantastical, or futuristic elements.

Three genres are covered by this umbrella term: Science Fiction, Fantasy, and Horror.

This term is also used to cover work that doesn’t fit exactly in one of these three genres, but moves between them.

Many of these publishers are interested in speculative fiction in general. Some publish just one of the genres covered by the speculative fiction umbrella such as horror. Others publish many genres and types of books. Others are just interested in work for younger readers or a specific combination of genres, like science fiction and romance, or Romantasy which has become a very popular genre.

Some are small companies, others are imprints of major publishing houses. They are not listed in any particular order.

Not all of them may be currently open to submissions. It is important to note that all of them meet the standards outlined in our guiding principles.

All of the publishers are only briefly described on this page, however if you click on the link, you will reach our full review of them, or if that full review has not been published yet, the link will direct to the publishers submission guidelines. The full reviews include submission information and links to their websites.

I must also note that between 2025 and 2026 many science fiction and horror publishers that were focused on this genre closed, either to submissions or entirely. But it is becoming more common for a press to publish these genres alongside a wider range of genres.

Subtle Body Press
Subtle Body Press is a small press that publishes novella length work. This is what they say they are looking for: “Show us something we haven’t seen before—but make it substantive and accessible.

But don’t limit yourself. We’re open to being pleasantly surprised, so give us your best and surprise us.” This is not a good fit for anything mainstream or strictly genre, you can get a good idea of what they’ve previously published here.
