What is Prince Andrew's Last Name
Prince Andrew's last name is Mountbatten-Windsor, the surname used by some members of the British royal family who do not hold a styled royal title. As a son of Queen Elizabeth II and a prince of the United Kingdom, his formal family name is Mountbatten-Windsor, reflecting the 1960 royal declaration that this surname applies to descendants of Queen Elizabeth II and Prince Philip not entitled to royal style and title. This name combines the House of Mountbatten and the House of Windsor. Below is a breakdown of his full name, title, and the origin and use of the Mountbatten-Windsor surname in official and private contexts.
Prince Andrew's Full Name and Title
Full name and style
Prince Andrew is formally known as His Royal Highness Prince Andrew, Duke of York. In the British royal family, a person's last name can depend on their title and whether they are a working royal or not. Working royals who carry styled titles—such as Prince, Princess, or Duke—may use those titles as their public identification rather than a family surname. The family name Mountbatten-Windsor is used by other descendants for legal and administrative purposes.
Royal surname conventions
British royal family members may use different names depending on context: the House name, the surname, or a territorial designation. Key distinctions include:
- House of Windsor: The name adopted by King George V in 1917, replacing Saxe-Coburg and Gotha during World War I.
- Mountbatten-Windsor: Formed through the 1960 declaration by Queen Elizabeth II and Prince Philip to reconcile the House of Windsor with Prince Philip's House of Mountbatten.
- Royal title vs. surname: Working royals such as Prince William and Prince Harry historically used Wales or their military ranks for formal purposes, while the broader family use Mountbatten-Windsor for official matters.
The Origins of Mountbatten-Windsor
The surname Mountbatten-Windsor emerged from a need to create a shared family name for descendants of Queen Elizabeth II who were not styled as royal highnesses. In 1960, Queen Elizabeth II and Prince Philip declared that descendants who did not hold the style of Royal Highness or Serene Highness would bear the surname Mountbatten-Windsor. This policy balanced the traditions of the long-standing House of Windsor with Prince Philip's heritage, establishing a consistent surname for civil, legal, and administrative use across the extended family.
Practical Use of the Surname in Documents and Legal Contexts
In practice, members of the royal family often do not use a surname in everyday life or in formal royal capacities. For instance, Prince Andrew served as a Royal Navy officer under the service name 'Prince Andrew' without needing to use a surname. However, documents such as marriage certificates, legal filings, and official records may require a surname, in which case Mountbatten-Windsor is typically used for those not entitled to a styled title. Service personnel in the armed forces may also use a surname for administrative purposes, which can differ from the ceremonial royal name.

Clarifications and Common Misunderstandings
Some assume that royal children automatically inherit a traditional surname in the way commoners do, but royal naming conventions are distinct. Prince Andrew is commonly referred to by his title, and his last name is not used in day-to-day royal duties. The name Mountbatten-Windsor applies broadly to descendants who lack styled titles, while direct male-line descendants might also carry the name of their father's peerage or military unit in certain formal contexts. Public records, legal documents, and genealogical sources typically cite Mountbatten-Windsor as the family name for those without royal styling.
