Corporatism, also known as corporativism, is a system of economic, political, or social organization that involves association of the people of society into corporate groups, such as agricultural, business, ethnic, labor, military, patronage, or scientific affiliations, on the basis of common interests. Corporatism is theoretically based upon the interpretation of a community as an organic body. The term corporatism is based on the Latin root word "corpus" meaning "body".

In 1881, Pope Leo XIII commissioned theologians and social thinkers to study corporatism and provide a definition for it. In 1884 in Freiburg, the commission declared that corporatism was a "system of social organization that has at its base the grouping of men according to the community of their natural interests and social functions, and as true and proper organs of the state they direct and coordinate labor and capital in matters of common interest."

One of the main types of corporatism is economic tripartism involving negotiations between business, labour, and state interest groups to establish economic policy.
