Weird fiction is a subgenre of speculative fiction written in the late 19th and early 20th century. It can be said to encompass the ghost story and other tales of the macabre. Weird fiction is distinguished from horror and fantasy in that it predates the niche marketing of genre fiction. Because genre or stylistic conventions had not been established, weird tales often blend the supernatural, mythical, and even scientific. British authors who have embraced this style have often published their work in mainstream literary magazines even after American pulp magazines became popular. Popular weird fiction writers included W.H Hodgson, H. P. Lovecraft, Lord Dunsany, Arthur Machen, M. R. James, and Clark Ashton Smith.
Although "weird fiction" is chiefly a historical description for works through the 1930s, the term has also been used since the 1980s, sometimes to describe slipstream fiction that blends horror, fantasy, and science fiction.
The true weird tale has something more than secret murder, bloody bones, or a sheeted form clanking chains according to rule. A certain atmosphere of breathless and unexplainable dread of outer, unknown forces must be present; and there must be a hint, expressed with a seriousness and portentousness becoming its subject, of that most terrible conception of the human brain--a malign and particular suspension or defeat of those fixed laws of Nature which are our only safeguard against the assaults of chaos and the daemons of unplumbed space.
The pulp magazine Weird Tales published many such stories in the United States from March 1923 to September 1954. S. T. Joshi describes several subdivisions of the weird tale: supernatural horror (or fantastique), the ghost story, quasi science fiction, fantasy, and ambiguous horror fiction and argues that "the weird tale" is primarily the result of the philosophical and aesthetic predispositions of the authors associated with this type of fiction.
Although Lovecraft was one of the few early 20th-century writers to describe his work as "weird fiction," the term has enjoyed a contemporary revival in New Weird fiction. For example, China Miéville often refers to his work as weird fiction. Many horror writers have also situated themselves within the weird tradition, including Clive Barker, who describes his fiction as fantastique, and Ramsey Campbell, whose early work was deeply influenced by Lovecraft.
The following notable authors have been described as writers of weird fiction:
The New Weird 
It has been suggested by some authors, predominantly Ann and Jeff VanderMeer, that Weird fiction has seen a recent resurgence, a phenomenon they term the New Weird. Tales which fit this category, as well as extensive discussion of the phenomenon, appear in their anthology The New Weird.
