The monarchy of Jamaica is a constitutional system of government in which a hereditary monarch is the sovereign and head of state of Jamaica. The terms "Crown in Right of Jamaica", "Her Majesty in Right of Jamaica", or "The Queen in Right of Jamaica" may also be used to refer to the entire executive of the government of Jamaica. Though the Jamaican Crown has its roots in the British Crown, it has evolved to become a distinctly Jamaican institution, represented by its own unique symbols.
