在阿兹特克神话中，西乌阿科阿特莉(Cihuacoatl)(“女人蛇”也称：Cihuacóatl)是数位母神和生育女神之一，西乌阿科阿特莉有时被称为“奎拉兹特莉”(Quilaztli)。

西乌阿科阿特莉尤其与接生婆有关联。她与奎拉兹特莉配对，被认为是查尔墨卡(Chalmeca)人的保护者和库尔瓦坎市(Culhuacan)的守护神。她帮羽蛇神魁札尔科亚特尔(Quetzalcoatl)通过磨碎前代的骨骼，并混合他的血液创建了现在的人类。她也是米什科阿特利(Mixcoatl，又叫伊斯塔克·米什科阿特利、卡马什特利)的母亲，被她遗弃在一个十字路口。传统说，她经常回到那里哭泣失去的儿子，只找到一把人祭刀。

In Aztec mythology, Cihuacoatl [siwaˈkoːaːt͡ɬ] ("snake woman"; also Cihuacóatl) was one of a number of motherhood and fertility goddesses. Cihuacoatl was sometimes known as Quilaztli.

Cihuacoatl was especially associated with midwives, and with the sweatbaths where midwives practiced. She is paired with Quilaztli and was considered a protectress of the Chalmeca people and patroness of the city of Culhuacan. She helped Quetzalcoatl create the current race of humanity by grinding up bones from the previous ages, and mixing it with his blood. She is also the mother of Mixcoatl, whom she abandoned at a crossroads. Tradition says that she often returns there to weep for her lost son, only to find a sacrificial knife.
