The head of government is either the highest or second highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, autonomous region, or other government who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. "Head of government" is often differentiated from "head of state" (as in article 7 of the Vienna Convention on the Law of Treaties, article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents and the United Nations protocol list),[1][2][3] as they may be separate positions, individuals, or roles depending on the country.

The authority of a head of government, such as a president, chancellor, or prime minister and the relationship between that position and other state institutions, such as the relation between the head of state and of the legislature, varies greatly among sovereign states, depending largely on the particular system of the government that has been chosen, won, or evolved over time.

In most parliamentary systems, including constitutional monarchies, the head of government is the de facto political leader of the government, and is answerable to at least one chamber of the legislature. Although there is often a formal reporting relationship to a head of state, the latter usually acts as a figurehead who may take the role of chief executive on limited occasions, either when receiving constitutional advice from the head of government or under specific provisions in a constitution.
