Amorphophallus konjac, commonly known as konnyaku or konjac, is a species of flowering plant in the family Araceae. In English, it is also referred to as devil's tongue, voodoo lily, snake palm, or elephant yam.

The perennial species forms a corm, the stem of which produces a purplish flower. It is native to China and is cultivated in East and Southeast Asia. Food made from the corm is known by its Japanese name, konnyaku. It can be made into white or black cake, as well as a kind of noodle called shirataki.
