Charles III reigns as king of 15 independent countries known as the Commonwealth realms. He resides primarily in the oldest and most populous realm, the United Kingdom, and is represented in the other countries by the following viceregal representatives. The monarch is also represented in each of the Canadian provinces, Australian states, British overseas territories, Crown dependencies, and the states in free association with New Zealand.
Commonwealth realms
= Governors-general
== Counsellors of state
=In the United Kingdom, the sovereign appoints counsellors of state to act on the monarch's behalf when he or she is not present in the country or unable for other reasons to perform royal constitutional functions.
Crown dependencies
The Crown dependencies are possessions of the Crown of the United Kingdom, not of the government of the United Kingdom, and the British monarch is head of state, represented by lieutenant governors.
British Overseas Territories
In the 14 British Overseas Territories, the King of the United Kingdom is represented by either an administrator, a commissioner, or a governor.
States in free association with New Zealand
In the Realm of New Zealand, the Cook Islands have a king's representative to represent the King of New Zealand. Niue is entitled to the same, but, under the Niue Constitution Act, the monarch is represented by New Zealand's governor-general, who represents the King of New Zealand.
Sub-national representatives
= Australia
=In the six Australian states, the King of Australia is represented by a governor. As administrators of Australian territories represent the governor-general of Australia, they are not included here.
= Canada
=In the 10 Canadian provinces, the King of Canada is represented by a lieutenant governor. As the commissioners of the Canadian territories represent the Canadian king-in-Council (the federal government), rather than the monarch directly, they are not included here.
