Femme fatale:

Wikipedia:

"A femme fatale, sometimes called a maneater ..., is a ... mysterious, beautiful, and seductive woman whose charms ensnare her lovers, often leading them into compromising, deadly traps ...

The femme fatale was a common figure in the European Middle Ages, often portraying the dangers of unbridled female sexuality. The pre-medieval inherited biblical figure of Eve offers an example, as does the wicked, seductive enchantress typified in Morgan le Fay. The Queen of the Night in Mozart's The Magic Flute shows her more muted presence during the Age of Enlightenment."
