Christmas Horror is a subgenre of horror that combines the festive elements of Christmas with themes of fear and dread. It often features traditional symbols of the holiday, such as Santa Claus, Christmas trees, and holiday decorations, twisted into sinister forms. This genre explores the contrast between the joy of the season and the darkness that can lurk beneath the surface. Films and stories in this genre may include supernatural elements, slasher themes, or psychological horror. Popular examples include Black Christmas and Krampus, which highlight the potential for terror during what is typically a joyful time of year. Christmas Horror challenges the notion of safety and comfort associated with the holiday season.
