Anne de Mowbray, 8th Countess of Norfolk, later Duchess of York and Duchess of Norfolk was the child bride of Richard of Shrewsbury, Duke of York, one of the Princes in the Tower. She died at the age of eight.

Duchess of York is the principal courtesy title held by the wife of the Duke of York. Three of the eleven Dukes of York either did not marry or had already assumed the throne prior to marriage, while two of the Dukes married twice; therefore, there have been only ten Duchesses of York.
