Duke of Northumberland is a noble title that has been created three times in English and British history, twice in the Peerage of England and once in the Peerage of Great Britain. The current holder of this title is Ralph Percy, 12th Duke of Northumberland.

The title was first created in the Peerage of England in 1551 for John Dudley, 1st Earl of Warwick. He had already been created Viscount Lisle in 1543 and Earl of Warwick in 1547, also in the Peerage of England. In 1553, Dudley advanced the claim of his daughter-in-law, Lady Jane Grey, to the English throne, but when she was deposed by Queen Mary I, Dudley was convicted of high treason and executed. An illegitimate son of one of his younger sons, Robert Dudley, 1st Earl of Leicester, Sir Robert Dudley, claimed the dukedom when in exile in Italy. On 9 March 1620 the Emperor Ferdinand II officially recognised the title, an act which infuriated James I of England.

George FitzRoy, 1st Earl of Northumberland, an illegitimate son of king Charles II, was created Duke of Northumberland in the Peerage of England in 1683. He had already been created Baron of Pontefract, Viscount Falmouth and Earl of Northumberland in 1674, also in the Peerage of England. However, all the titles became extinct on his death in 1716 as he left no heirs.

In 1716 Philip Wharton, 1st Duke of Wharton, was created Duke of Northumberland, Marquess of Woburn, Earl of Malmesbury and Viscount Winchendon in the Jacobite Peerage, by The Old Pretender. The title had no legal validity in the Kingdom of Great Britain.
