Every Country where King Charles III is Head of State

Many people believe that as the King of England, Charles III’s sovereignty stops at the borders of the United Kingdom. However, this is not true. As of May 2024, 15 separate Commonwealth realms look to King Charles III as their monarch. 

While his role is mostly ceremonial, King Charles III is the “Head of the Commonwealth,” so he remains the monarch for 15 countries worldwide. Let’s identify these 15 Commonwealth realms and see where they are located across North America, Europe, and Oceania (Pacific Ocean).
