The title Duke of Richmond (named after Richmond in North Yorkshire) has been created several times in the Peerage of England. The Dukedom was first created (as Duke of Richmond and Somerset) for the illegitimate son of King Henry VIII, Henry Fitzroy, upon whose death it became extinct. The next creation was for the second Duke of Lennox in 1623; it became extinct upon his death. It was created again for the fourth Duke of Lennox. Upon the death of the sixth Duke of Lennox, both Dukedoms became extinct. The next creation was in August 1675 for Charles Lennox, an illegitimate son of King Charles II, who was further created Duke of Lennox a month later. The Duke of Richmond and Lennox was created Duke of Gordon in 1876. Thus, the Duke holds three dukedoms, more than any other person in the realm.

The subsidiary titles are: Earl of March (created 1675), Earl of Darnley (1675), Earl of Kinrara (1876), Baron Settrington, of Settrington in the County of York (1675), and Lord Torbolton (1675). The titles Earl of March and Baron Settrington were created in the peerage of England along with the Dukedom of Richmond. The titles Earl of Darnley and Lord Torbolton were created in the Peerage of Scotland along with the Dukedom of Lennox. Finally, the title Earl of Kinrara was created in the peerage of the United Kingdom with the Dukedom of Gordon. The eldest son of the Duke uses the courtesy title Earl of March and Kinrara. Before the creation of the Dukedom of Gordon, the courtesy title used was Earl of March.

The Dukes of Richmond, Lennox and Gordon are normally styled Duke of Richmond and Gordon. Before the creation of the Dukedom of Gordon they were styled Duke of Richmond and Lennox.
