What is the name of Santa's wife?

Santa Claus’s wife is traditionally called Mrs. Claus.

She is a supporting figure in the Western Christmas tradition, usually portrayed as Santa’s companion at the North Pole. Stories and illustrations commonly place her in Santa’s workshop, where she may bake, manage household tasks, help prepare gifts, or care for the reindeer while Santa travels.

Mrs. Claus does not have one universally fixed first name. Depending on the story, she has been called Mary Claus, Mary Christmas, Mother Christmas, Mrs. Santa Claus, or simply Mrs. Santa. Those variations explain why names such as Clara or Martha may appear in particular books, films, or local retellings, but they are not the standard answer to the general trivia question.

Her character became more prominent in 19th- and 20th-century literature, illustrations, advertising, television, and film. Unlike Santa Claus, whose mythology draws on Saint Nicholas and several European traditions, Mrs. Claus is primarily a later fictional partner created within Christmas storytelling.
