A vegetable lantern commonly carved from a pumpkin, typically as a Halloween decoration. The pumpkin has a face or image carved into it, and the insides are usually scooped out so that a candle can be placed inside to illuminate the carving.
The practice originated from Ireland where they would use turnips or mangelwurzel to craft these lanterns for Halloween. Irish immigrants brought this tradition to North America where it led to the development of carving pumpkins to make jack-o'-lanterns.
