The traditional name for Santa Claus’s wife in popular Christmas stories is Mrs. Claus.
Mrs. Claus is a modern Christmas character who is usually portrayed as Santa’s supportive wife and companion at the North Pole. Stories commonly show her baking, managing household activities, caring for reindeer, or helping organize the Christmas operation while Santa delivers presents.
Her exact origins are less clear than those of Santa Claus. One early literary reference appeared in the 19th century, and later poems, books, advertisements, films, and television programs gradually established her as a familiar part of Christmas folklore. Unlike Saint Nicholas, Mrs. Claus does not correspond to a well-documented historical person.
Different stories give her first names, but no single first name is universally canonical. “Mrs. Claus” remains the stable and widely recognized form, which is why versions that call her Jessica or another name belong to particular adaptations rather than the tradition as a whole.
