The figure of Mother Goose is the imaginary author of a collection of fairy tales and nursery rhymes often published as (Old) Mother Goose's Rhymes. As a character, she appears in one nursery rhyme. A Christmas pantomime called Mother Goose is often performed in the United Kingdom. The so-called "Mother Goose" rhymes and stories have formed the basis for many classic British pantomimes. Mother Goose is generally depicted in literature and book illustration as an elderly country woman in a tall hat and shawl, a costume identical to the peasant costume worn in Wales in the early 20th century, but is sometimes depicted as a goose (usually wearing a bonnet).
