Leng is a fictional cold arid plateau in the Cthulhu Mythos, whose location seems to vary entirely from story to story. The Plateau of Tsang, referenced by H. P. Lovecraft and other authors, is probably a region of Leng.
Abdul Alhazred describes it as a place where different realities converge, which might explain why its precise location cannot be pinned down.
Appearances in Lovecraft's work
- Lovecraft first described Leng in "The Hound" (1922) in which the dreaded Necronomicon places it in Central Asia and says it is inhabited by a human corpse-eating cult.
- In The Dream-Quest of Unknown Kadath, (1926) the Plateau of Leng is located in the north of the Dreamlands, an alternate dimension accessible only in sleep. It is inhabited by the High Priest Not to Be Described, who dwells alone in a prehistoric monastery, and by a race of degenerate, goatish humans who are feared by all other men.
- In At the Mountains of Madness, an expedition from Miskatonic University explores a plateau in Antarctica and discovers an ancient and apparently abandoned city built by the Elder Things. One member of the expedition, who has encountered references to the Plateau of Leng in ancient texts, forms the hypothesis that the plateau they are exploring is Leng. In common with the High Priest's abode in The Dream-Quest of Unknown Kadath, the walls of the buildings atop the plateau are covered with detailed frescos that are disturbing to read. However, it is never explicitly stated in the text—or in any of Lovecraft's later works—that this Antarctic city actually is Leng. In fact, it seems more likely that the city is simply an outpost of the Elder Things which came to Earth not to conquer but to live in isolation.
- Leng is also (briefly) mentioned in "The Horror in the Museum", "Celephaïs", and "The Whisperer in Darkness".
- In Stephen King's novel Needful Things, Mr. Gaunt gives Ace Merrill some cocaine said to be fabricated in "the plains of Leng", though no other explanations are given. The novel also contains other references to Lovecraft's work. It is mentioned again in his novel The Eyes of the Dragon, where it is described as the place where Flagg's spellbook was written, by a man named Alhazred. This implies that Flagg's spellbook is the Necronomicon itself.
- In Brian Lumley's Cthulhu Cycle Deities Novels the plains of Leng are supposed to be located in Earth's dreamland.
- In the Pathfinder Roleplaying Game, Leng is a demi-plane, or pocket dimension, that exists adjacent to the world of Golarion. It closely resembles the Leng described in The Dream-Quest of Unknown Kadath.

- In Kim Newman's Richard Jeperson short story "Soho Golem", an occultist and priest of Nyarlathotep holds the noble title "Lord Leaves of Leng".
- Leng is mentioned by an Iranian agent in "A Colder War" (1997) by Charles Stross.
- In Charles Stross's short story "Pimpf", the "Language of Leng" is inserted into the programming code of Neverwinter Nights in order to ensnare the souls of players.
