Key answer
Prince Charles's surname is Mountbatten-Windsor. This family name is used by some working members of the royal family for official purposes such as marriage registration and passports, but it is distinct from the house names and styles by which he is commonly known.
Origin and legal adoption of Mountbatten-Windsor
The surname Mountbatten-Windsor originated from the combination of the names of two formerly separate royal lineages. Princess Elizabeth and Prince Philip declared this blended name through a Privy Council order in 1960. Before this 1960 decision, the royal house had been known by different names, shifting from Saxe-Coburg and Gotha to Windsor under wartime pressures, which illustrates how dynastic names can evolve in response to historical context.
1960 royal surname declaration
A 1960 declaration established that descendants of Queen Elizabeth II and Prince Philip not styled as Royal Highness or titled as Prince or Princess would bear the surname Mountbatten-Windsor. The declaration did not affect the names of children who hold royal styles and titles, which helps explain why the rules around the name can appear inconsistent at first glance.

How the name differs from house names and titles
Although the legal surname is Mountbatten-Windsor, members of the royal family are generally known by house names and honorifics. Prince Charles was born into the House of Windsor and held the title Prince of Wales. Explore how these public-facing identities shape media usage and public perception, sometimes overshadowing the technical surname in day-to-day communication.
House names versus surnames
- House of Windsor: designation used for the family in public, ceremonial, and some administrative contexts
- Mountbatten-Windsor: legal surname used in official documentation for certain family members
- House of Saxe-Coburg and Gotha: earlier royal house name before World War I changes
- House of Hanover: historical house name linked to earlier British royal ancestry
Use of the surname in practice
Mountbatten-Windsor appears on official documents such as marriage notices and passports for eligible family members. In daily life, Prince Charles is commonly referred to by his title, HRH The Prince of Wales or The King, rather than by the legal surname. This practice aligns with centuries of royal protocol that prioritizes styles and house names over personal surnames.
Historical context and earlier naming conventions
The evolution of the royal family's naming conventions reflects broader changes in law, public sentiment, and international relations. From the Germanic associations of Saxe-Coburg and Gotha to the more English-centric Windsor during the First World War, and finally to the blended Mountbatten-Windsor, these shifts reveal how monarchy adapts while maintaining continuity.
Name transitions timeline
House names have shifted in response to war, public opinion, and legislative change. The move from Saxe-Coburg and Gotha to Windsor during the First World War was driven by anti-German sentiment. Later adjustments, such as the 1960 declaration, balanced family identity with administrative clarity.
| Date or Period | House Name or Surname Used | Why It Matters |
|---|---|---|
| Pre-1917 | Saxe-Coburg and Gotha | Reflected German ancestry of the royal family |
| 1917–1952 | Windsor | Shifted to an English house name during WWI |
| 1952–1960 | Windsor | Continued use after accession of Elizabeth II |
| From 1960 for some descendants | Mountbatten-Windsor | Formal blended surname established by declaration |
