# List of titles and honours of William, Prince of Wales

William, Prince of Wales has received numerous titles, decorations and honorary appointments both during his time as Duke of Cambridge and Prince of Wales. Each is listed below; where two dates are shown, the former indicates the date of receiving the title or award (the title as Prince William of Wales being given as from his birth) and the latter indicates the date of its loss or renunciation.

## Royal and noble titles and styles

William has been a British prince since birth, and was known as "Prince William of Wales" until 2011. On his wedding day, 29 April 2011, his grandmother Elizabeth II created him Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus. The letters patent granting these titles were issued on 26 May that year.
As the eldest son of the monarch, William automatically became Duke of Cornwall, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles, and Prince and Great Steward of Scotland on the accession of his father on 8 September 2022. From 8 to 9 September, William was styled as "His Royal Highness The Duke of Cornwall and Cambridge". On 9 September, Charles III announced the creation of William as Prince of Wales. William has since been known as "His Royal Highness The Prince of Wales", except in Scotland where he has been styled as "His Royal Highness The Duke of Rothesay". The letters patent formally granting him this titles of Prince of Wales and Earl of Chester were issued on 13 February 2023. The usage of the title Prince of Wales has been subject to some controversy over the past decades, primarily from Welsh nationalists.

### Surname

As a British prince, William does not use a surname for everyday purposes. For formal and ceremonial purposes, children of the Prince of Wales use the title "prince" or "princess" before their forename and follow it with their father's territorial designation. Thus, before becoming a duke when he married, Prince William was styled "Prince William of Wales". Such territorial designations are discarded by women when they marry and by men if they become peers in their own right, such as when Prince William was made a duke.
Although the name of the royal house is Windsor, the surname Mountbatten-Windsor belongs to all the children and male-line descendants of Queen Elizabeth II and Prince Philip, and is used, if needed, by those who do not have the style of Royal Highness and the title Prince or Princess; when a female descendant marries, she traditionally takes her husband's surname from that point onward, and their children take their father's. Both Princes William and Harry used Wales as their surname for military purposes; this continued to be the case for William after his creation as Duke of Cambridge.

## Banners, flags, and standards
### As heir apparent

The banners used by the Prince of Wales vary depending upon location. His personal standard is the Royal Standard of the United Kingdom differenced as in his arms with a label of three points Argent, and the escutcheon of the arms of the Principality of Wales in the centre. It is used outside Wales, Scotland, Cornwall, and Canada, and throughout the entire United Kingdom when the prince is acting in an official capacity associated with the United Kingdom Armed Forces.
The personal flag for use in Wales is based upon the Royal Badge of Wales (the historic arms of the Kingdom of Gwynedd), which consist of four quadrants, the first and fourth with a red lion on a gold field, and the second and third with a gold lion on a red field. Superimposed is an escutcheon Vert bearing the single-arched coronet of the Prince of Wales.
In Scotland, the personal banner used since 1974 is based upon three ancient Scottish titles: Duke of Rothesay (heir apparent to the King of Scots), High Steward of Scotland and Lord of the Isles. The flag is divided into four quadrants like the arms of the Chief of Clan Stewart of Appin; the first and fourth quadrants comprise a gold field with a blue and silver checkered band in the centre; the second and third quadrants display a black galley on a silver field. The arms are differenced from those of Appin by the addition of an inescutcheon bearing the tressured lion rampant of Scotland; defaced by a plain label of three points Azure to indicate the heir apparent.
In Cornwall, the banner is the arms of the Duke of Cornwall: "Sable 15 bezants Or", that is, a black field bearing 15 gold coins.
In Canada, a personal heraldic banner for the Prince of Wales was first issued in 2011, consisting of the shield of the Arms of Canada defaced with both a blue roundel of the Prince of Wales's feathers surrounded by a wreath of gold maple leaves, and a white label of three points.

### Former standards

Prior to the accession of his father, William used a banner derived from his arms, for use outside of Scotland and Canada. There was a variation of this used when in Scotland. In 2011, the Canadian Heraldic Authority introduced a personal heraldic flag for the Duke of Cambridge's use in Canada. It is the Royal Arms of Canada in banner form defaced with a blue roundel surrounded with a wreath of gold maple leaves and shells within which is a depiction of a "W" surmounted by a coronet. Above the roundel is a white label of three points, charged with a red shell.
