Prince Adolphus, Duke of Cambridge (Adolphus Frederick; 24 February 1774 – 8 July 1850), was the tenth child and seventh son of George III and Queen Charlotte. He held the title of Duke of Cambridge from 1801 until his death. He also served as Viceroy of Hanover on behalf of his brothers George IV and William IV. His granddaughter, Mary of Teck was the Queen consort of George V.

Prince Adolphus was born at Buckingham Palace. He was tutored at home before being sent to the University of Göttingen in Germany in summer 1786, along with his brothers Prince Ernest (created Duke of Cumberland in 1799) and Prince Augustus (created Duke of Sussex in 1801).

In 1791, he and Prince Ernest went to Hanover to receive military training under the supervision of the Hannoverian commander Field Marshal von Freytag. He rose to the ranks of colonel in 1794, to lieutenant general in 1798, and field marshal in 1813. George III appointed Prince Adolphus a Knight of the Garter on 6 June 1786 and created him Duke of Cambridge, Earl of Tipperary, and Baron Culloden on 17 November 1801.

The Duke served as colonel-in-chief of the Coldstream Regiment of Foot Guards (Coldstream Guards after 1855) from September 1805 and as colonel-in-chief of the 60th (The Duke of York's Own Rifle Corps) Regiment of Foot from January 1824.

After the death of Princess Charlotte in 1817, the Duke was set the task of finding a bride for his eldest unmarried brother, the Duke of Clarence (later William IV) in the hope of securing heirs to the throne -- Charlotte had been the only legitimate grandchild of George III, despite the fact that the King had twelve surviving children. After several false starts, the Duke of Cambridge settled on Princess Adelaide of Saxe-Meiningen. The Duke of Clarence agreed with alacrity, and the way was cleared for the Duke of Cambridge to find a bride for himself.

The Duke of Cambridge was married first at Cassel, Hesse on 7 May and then at Buckingham Palace on 1 June 1818 to his second cousin Augusta (25 July 1797-6 April 1889), the third daughter of Friedrich III, Landgrave of Hesse-Cassel.

He was, as is shown in the list of issue below, the maternal grandfather of Mary of Teck, consort of George V. This makes Adolphus the great-great-grandfather of the present British monarch, Elizabeth II

From 1816 to 1837, the Duke of Cambridge served as viceroy of Hanover on behalf of his elder brothers, George IV and later William IV. When his niece, Queen Victoria succeeded to the British throne on 20 June 1837, the 123-year union of the crowns of Great Britain (the United Kingdom of Great Britain and Ireland from 1801) and Hanover ended. The Duke of Cumberland became King Ernest Augustus I of Hanover and the Duke of Cambridge returned to Britain.

The Duke of Cambridge died on 8 July 1850 at Cambridge House, Piccadilly, London, and was buried at Kew. His remains were later removed to St. George's Chapel, Windsor. His only son, Prince George, succeeded to his peerages.
