Charles, Prince of Wales is heir apparent to the monarch of the United Kingdom, Canada, Australia, and New Zealand.
 Following Charles III's accession to the throne in September 2022, a petition was launched calling for the abolition of the title "Prince of Wales", which had received over 35,000 signatures
 Most monarchies refer to the heir apparent of their thrones with the descriptive term of crown prince or crown princess, but they may also be accorded with a more specific substantive title: such as Prince of Orange in the Netherlands, Duke of Brabant in Belgium, Prince of Asturias in Spain (also granted to heirs presumptive), or the Prince of Wales in the United Kingdom; former titles include Dauphin in the Kingdom of France, and Tsesarevich in Imperial Russia
