Nuit (alternatively Nu, Nut, or Nuith) is a goddess in Thelema, the speaker in the first chapter of The Book of the Law, the sacred text written or received in 1904 by Aleister Crowley.

[1] Within this system, Nuit is one part of a triadic cosmology, along with Hadit (her masculine counterpart), and Ra-Hoor-Khuit, the Crowned and Conquering Child, which are depicted on the Stele of Revealing.

[8] Manon Hedenborg-White writes that "[...] Nuit and Hadit are constructed as gendered opposites in ritual and literature, and their divine functions and attributes are linked to their sex.

"[9] She observes that Claiming that Nuit is female and receptive and Hadit is male and active is thus not a mere description, but a performative utterance that creates these deities as gendered in the minds of those who experience them, and reproduces assumptions about what femininity and masculinity is.

[10] She goes on to note the practitioners of Thelema may subvert this view through polytheism, incorporating deities such as Kali from Hinduism as well as the Greek god Pan to represent different forms of femininity and masculinity.
