Jack Frost

Personification of Frost in English/Norse Folklore

Jack Frost is the personification of frost and cold in English and Scandinavian folklore. Appearing as a young boy or mischievous old man, he draws frost ferns on winter windowpanes and nips at noses and toes. The name first appeared in 17th-century England as a British variant of the broader frost-personification tradition (Norse Jökull, Russian Morozko). He has become a perennial character in modern films and animation.
