Which literary subgenre is H. P. Lovecraft especially associated with? He is especially associated with weird fiction.

Weird fiction blends horror, fantasy, and sometimes science fiction in stories that unsettle ordinary ideas about reality. Rather than relying only on familiar ghosts or vampires, it often presents strange forces, alien entities, and threats that human beings cannot fully understand.

Lovecraft helped popularize the term through essays such as “Supernatural Horror in Literature,” written in the 1920s. His stories frequently replace conventional supernatural explanations with cosmic ones, portraying humanity as fragile and insignificant in a vast, largely indifferent universe.

Lovecraft is also linked with cosmic horror, Lovecraftian horror, dark fantasy, and horror fiction. Those labels overlap, but weird fiction is the broader literary subgenre most directly associated with his work and with the pulp magazine Weird Tales, where many of his stories appeared.
