Campanula rapunculus, common name rampion bellflower, rampion, or rover bellflower, is a species of bellflower (Campanula) in the family Campanulaceae.

This species was once widely grown in Europe for its leaves, which were used like spinach, and its parsnip-like root, which was used like a radish. The Brothers Grimm's tale Rapunzel took its name from this plant.
