A coronation crown is a crown used by a monarch when being crowned. In some monarchies, monarchs have or had a number of crowns for different occasions, such as a coronation crown for the moment of coronation and a state crown for general usage in state ceremonial.

A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it. A specific type of crown is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium.
