"The Grand Old Duke of York" is an English children's nursery rhyme, often performed as an action song. The eponymous duke has been argued to be a number of the bearers of that title, particularly Prince Frederick, Duke of York and Albany (1763–1827), and its lyrics have become proverbial for futile action. It has a Roud Folk Song Index number of 742.

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.
