The Duke of Rutland is a title in the peerage of England.

The subsidiary titles of the Duke are: Marquess of Granby (created 1703), Earl of Rutland (1525), Baron Manners, of Haddon in the County of Derby (1679), and Baron Roos of Belvoir, of Belvoir in the County of Leicester (1896). The title Baron Roos of Belvoir is in the United Kingdom peerage; the remaining titles being in the peerage of England. The most senior subsidiary title, Marquess of Granby, is the courtesy title of the Duke's eldest son and heir.

The title Earl of Rutland was created for Edward Plantagenet, (1373-1415), son of Edmund of Langley, Duke of York, and grandson of King Edward III. Upon the Duke's death in 1402 Edward became Duke of York. The title Earl of Rutland fell in to disuse upon his death at the battle of Agincourt. It was assumed by other members of the House of York including first earl's nephew Richard Plantagenet, Duke of York, the father of King Edward IV.

Richard Plantagenet's granddaughter, Anne St Leger , married George Manners, 12th Baron Roos (Ros) of Hamlake (or Helmsley), who had inherited the barony from his mother. The barony of 'de Ros of Hamlake, Truibut and Belvoir' (sometimes spelled Ros, Roos or de Roos) was created by Simon de Montfort with a writ of summons to the House of Lords for Robert de Ros (1223-1285) in 1264. The title may thus pass through the female line when there is no male heir. The title has passed into abeyance and been revived a number of times and is now held outside of the Manners family. The 12th Baron's son, Thomas Manners (c. 1488-1543), was created earl of Rutland in the peerage of England in 1525.

The 3rd earl, Edward Manners (c. 1548-1587), left no sons, and the barony of Ros, passed to the family of his daughter Elizabeth (d. 1591) who became the wife of William Cecil, earl of Exeter. Edward Manners successor as the 4th earl was his brother John (d. 1588). The barony of Ros was restored to the Manners family when Francis Manners, the 6th earl (1578-1632), inherited it in 1618 from his cousin William Cecil (1590-1618). However, Francis died without male issue and the assumption of the courtesy title of Lord Ros for the eldest son of subsequent earls appears to have had no legal basis.

The 9th earl John Manners, (1638-1711), was created Duke of Rutland and Marquess of Granby in 1703 by Queen Anne.The eldest son of the duke may use Marquess of Granby as a courtesy title. The most notable Marquess of Granby was John Manners, (1721-1770). An accomplished soldier and popular figure of his time, his title was honoured by being used by a very large number of public houses throughout Britain.

The family still own Haddon Hall and Belvoir Castle, both of which are open to the public.
