|Dukedom of Windsor|
|Creation date||8 March 1937|
|Peerage||Peerage of the United Kingdom|
|First holder||Prince Edward|
|Remainder to||the 1st Duke's heirs male of the body lawfully begotten|
Duke of Windsor was a title in the Peerage of the United Kingdom. It was created on 8 March 1937, for former King Edward VIII, following his abdication on 11 December 1936. The dukedom takes its name from the town where Windsor Castle, a residence of English monarchs since the time of Henry I, following the Norman Conquest, is situated. Windsor has been the house name of the royal family since 1917.
King Edward VIII abdicated on 11 December 1936, so that he could marry the American divorcée Wallis Simpson. At the time of the abdication, there was controversy as to how the former King should be titled. The new King George VI apparently brought up the idea of a title just after the abdication instrument was signed, and suggested using "the family name". Neither the Instrument of Abdication signed by Edward VIII on 10 December 1936, nor its enabling legislation, His Majesty's Declaration of Abdication Act 1936, indicated whether the king was renouncing the privileges of royal birth as well as relinquishing the throne. On 12 December 1936, at the Accession Council of the Privy Council of the United Kingdom, George VI announced he was to make his brother the "Duke of Windsor" with the style of Royal Highness. That declaration is recorded in the London Gazette. The Dukedom was formalised by Letters Patent on 8 March 1937. Edward, as a royal duke, could neither stand for election to the House of Commons nor speak on political subjects in the House of Lords. On 3 June 1937, Edward married Wallis Simpson, who upon their marriage became the Duchess of Windsor. Following his abdication, Edward and Wallis lived in exile in Paris, France. Edward died in 1972, upon which the Dukedom of Windsor went extinct.

As the Royal Arms go hand-in-hand with the crown, the undifferentiated Royal Arms passed to George VI. It was and is common heraldic practice for the eldest son to differentiate his arms in his father's lifetime, but the Duke of Windsor was left in the unusual position of an eldest son needing to difference his arms after his father's death. This was done by means of a label argent of three points, bearing on the middle point an imperial crown proper.
