A nursery rhyme is a traditional poem or song for children in Britain and many other countries, but usage of the term dates only from the late 18th/early 19th century. The term Mother Goose rhymes is interchangeable with nursery rhymes.

Mother Goose is a character that originated in children's fiction, as the imaginary author of a collection of French fairy tales and later of English nursery rhymes. She also appeared in a song, the first stanza of which often functions now as a nursery rhyme. The character also appears in a pantomime tracing its roots to 1806.
