Who holds the title Crown Prince of the United Kingdom
There is no Crown Prince of the United Kingdom; the heir is titled Prince of Wales and is the oldest son of the monarch. Since 8 September 2022, that role belongs to William, Prince of Wales, born 21 June 1982, elder son of King Charles III. Succession follows absolute primogeniture for those born after 28 October 2012, but the title used by the heir remains Prince of Wales rather than Crown Prince. This evergreen explainer clarifies the legal position, historical title usage, and current duties of the UK’s heir.
Current heir and title usage
Prince William, Prince of Wales
William, Prince of Wales, born 21 June 1982, is the first in line to the throne. He became heir when his father ascended the throne on 8 September 2022. The official title he holds is Prince of Wales, a designation historically granted to the male heir apparent since 1301. Though widely and informally called Crown Prince, that exact term is not used in UK law, official communications, most Crown Dependencies, or in most Commonwealth realms that share the same monarch.
Why not Crown Prince
The British system uses Prince of Wales for the heir apparent. The title dates to 1301, established by Edward I for his son, the future Edward II. In modern constitutional practice, Prince of Wales signals the heir’s distinctive public role. The term Crown Prince is not present in UK statutes and is generally reserved for other monarchies. The spouse of the Prince of Wales holds the title Princess of Wales, currently Catherine, Princess of Wales.
Line of succession and key people
Succession is governed by the Act of Settlement 1701, the Bill of Rights 1689, and the Succession to the Crown Act 2013, which introduced absolute primogeniture for individuals born after 28 October 2012. Below the Prince of Wales in the line are his children, then his siblings and their descendants. The following table summarizes the principal members of the current succession relevant to the heir and near heirs.
| Position | Name and title | Relationship to monarch | Birth date |
|---|---|---|---|
| Heir apparent | William, Prince of Wales | Eldest son of King Charles III | 21 June 1982 |
| Heir apparent’s heir | Prince George of Wales | Eldest child of William | 22 July 2013 |
| Heir apparent’s second child | Princess Charlotte of Wales | Second child of William | 5 May 2015 |
| Heir apparent’s third child | Prince Louis of Wales | Third child of William | 1 April 2 long="2018 |
| Next eligible sibling | Prince Harry, Duke of Sussex | Younger brother of William | 31 August 1984 |
| Next generation (George’s order) | Princess Augusta of Cambridge | Niece of William via younger brother Prince Edward | 8 January 2015 |
Constitutional role and practical duties
As heir, William undertakes constitutional and representational duties that prepare him for future kingship. These include supporting the monarch in ceremonies, attending key state occasions, and carrying out domestic and international engagements focused on issues such as mental health, conservation, and emergency services. He does not make political decisions or set policy; his role is nonpartisan and stabilising, designed to ensure continuity of public service across generations. When necessary, he may stand in for the monarch at state banquets, diplomatic audiences, and Trooping the Colour.
Accession and future title
Upon the King’s death or abdication, William will immediately become King, not Crown Prince. His regnal name will be used as king, as has happened with previous heirs who were Prince of Wales. The Queen Consort or any surviving wife would receive the title Queen Consort or revert to Princess of Wales, depending on personal choice and circumstances. The Duchy of Cornwall, which currently provides income to the Prince of Wales, will pass to the new king, and a new Prince of Wales will then be created for the next heir apparent, typically the king’s eldest son.
Common questions and clarifications

International context: how the UK differs
Several monarchies use the title Crown Prince or its equivalent; in Spain the heir is called Prince of Asturias, in Norway the heir is Crown Prince, and in Japan the heir is Crown Prince. The United Kingdom’s unique use of Prince of Wales reflects the distinct evolution of its nobility and constitutional history. The UK does not have legally defined ranks of Crown Prince or Crown Princess; the heir is styled Prince of Wales, and the heir’s spouse typically receives a corresponding princely title. No other Commonwealth realm currently uses the title Crown Prince.
