La Xtabay is a Yucatec Maya folklore tale about a demonic femme fatale who preys upon men in the Yucatán Peninsula. She is said to dwell in the forest to lure men to their deaths with her incomparable beauty. She is described as having beautiful, shining black hair that falls down to her ankles and wearing a white dress. One of the most accepted versions of the myth comes from a book, Diez Leyendas Mayas (1998), written by Jesus Azcorra Alejos.
