A monarch is the person who leads a monarchy. This is a form of government in which a state or polity is ruled or controlled by an individual who typically inherits the throne by birth and rules for life or until abdication. Monarchs may be autocrats (absolute monarchy) or ceremonial heads of state who exercise little or no power or only reserve power, with actual authority vested in a parliament or other body (constitutional monarchy).

The word monarch is derived from the Greek μονάρχης (from μόνος, "one/singular," and ἄρχων, "leader/ruler/chief") through the Latin: monarcha (mono: "one" + arch "chief") which referred to a single, at least nominally, absolute ruler. In current usage the word monarchy generally refers to a traditional system of hereditary rule, as elective monarchies are rare in the modern period (though they do still exist in Vatican City, Andorra and Malaysia).

Most states have at most one monarch at any given time, although a regent may rule when the monarch is a minor, not present, or otherwise incapable of ruling. Two monarchs have ruled simultaneously in some countries, as in the ancient Greek city-state of Sparta or the joint sovereignty of spouses or relatives (e.g. William and Mary of Kingdom of England and Scotland, Peter and Ivan of Russia, Charles and Joanna of Castile, etc.).
