Langsuir is a supernatural being of Malay and Indonesian folklore across the Malay Archipelago (Malaysia, Indonesia, Singapore), classed as a kind of vampire. It is the female revenant of a woman who died while pregnant or in childbirth.
She appears as a beautiful woman with ankle-length black hair, or as a disembodied head trailing entrails, and is said to prefer the blood of newborn boys. Protective measures include placing beads in the corpse’s mouth and needles in its palms; the earliest record is Skeat’s Malay Magic (1891).
