The governor-general of Jamaica is the representative of the Jamaican monarch, currently King Charles III, in Jamaica. The governor-general is appointed by the monarch on the recommendation of the prime minister of Jamaica. The functions of the governor-general include appointing ministers, judges, and ambassadors; giving royal assent to legislation passed by parliament; issuing writs for election.

The monarchy of Jamaica is a system of government in which a hereditary monarch is the sovereign and head of state of Jamaica. The current Jamaican monarch and head of state, since 8 September 2022, is King Charles III. As sovereign, he is the personal embodiment of the Jamaican Crown. Although the person of the sovereign is equally shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Jamaica and, in this capacity, he and other members of the royal family undertake public and private functions domestically and abroad as representatives of the Jamaican state. However, the monarch is the only member of the royal family with any constitutional role.
