Politics in Jamaica takes place in the framework of a representative parliamentary democratic constitutional monarchy. The 1962 Constitution of Jamaica established a parliamentary system whose political and legal traditions closely follow those of the United Kingdom. As the head of state, King Charles III - on the advice of the Prime Minister of Jamaica - appoints a governor-general as his representative in Jamaica. The governor-general has a largely ceremonial role, with their parliamentary function consisting simply of granting royal assent to bills which have passed Parliament. Jamaica constitutes an independent Commonwealth realm.

The prime minister of Jamaica is Jamaica's head of government, currently Andrew Holness. Holness, as leader of the governing Jamaica Labour Party (JLP), was sworn in as prime minister on 7 September 2020, having been re-elected as a result of the JLP's landslide victory in the 2020 Jamaican general election.
