The Twelve Demon Moons (十二鬼月 Jūnikizuki) is the main antagonistic faction of manga/anime series, Demon Slayer: Kimetsu No Yaiba. They are an organization of the twelve most powerful Demons in existence who are under the direct command of the Demon King, Muzan Kibutsuji.

The Twelve Demon Moons are divided into two groups, the Upper Moons and the Lower Moons, each group having six members each, with Upper Moon 1 being the strongest, and Lower Moon 6 being the weakest. Every member have their position and ranking within their division engraved into their eye, with the Lower Moons having the kanji of Lower (下) and the kanji of their ranking in one eye, whereas Upper Moons have the kanji of Upper Moon (上弦) in one eye and the kanji of their ranking in the other.

The members of the Twelve Kizuki are fluctuated, and Muzan can replace them or even kill them once he thinks it's necessary. The difference in strength between the most powerful Lower Moon and the weakest Upper Moon is extremely large, showing the power gap between both divisions.
