The Pontifical Commission for Vatican City State is the legislative body of Vatican City. It consists of a president, who also holds the title of President of the Governorate of Vatican City State and serves as the head of government of Vatican City, as well as seven other cardinals appointed by the pope for five-year terms.

A legislature is a deliberative assembly with the legal authority to make laws for a political entity such as a country, nation or city. They are often contrasted with the executive and judicial powers of government. Legislatures can exist at different levels of government–national, state/provincial/regional, local, even supranational. Countries differ as to what extent they grant deliberative assemblies at the subnational law-making power, as opposed to purely administrative responsibilities.
