This is a list of monarchs who were Freemasons, and lists individual monarchs chronologically under the countries they ruled, monarchs who ruled more than one country are listed under the one they are most known for, or the dominant nation in a personal union (i.e. Christian X listed under Denmark and not Iceland). Those listed below were members of a Freemason Lodge sometime during their lives. Some, like Alexander I of Russia, would later outlaw Freemasonry in their territories, while others would continue supporting the organization for the rest of their lives.
Karl II – Patron of the united Lodges of the dominions of the Electorate of Brunswick, Duchy of Mecklenburg, Principalities of Münster-Waldeck and Hildesheim
