This is a list of bodies that consider themselves to be authorities on standard languages, often called language academies. Language academies are motivated by, or closely associated with, linguistic purism and prestige, and typically publish prescriptive dictionaries,^[1] which purport to officiate and prescribe the meaning of words and pronunciations. A language regulator may also have a more descriptive approach, however, while maintaining and promoting (but not imposing) a standard spelling. Many language academies are private institutions, although some are governmental bodies in different states, or enjoy some form of government-sanctioned status in one or more countries. There may also be multiple language academies attempting to regulate and codify the same language, sometimes based in different countries and sometimes influenced by political factors.

Many world languages have one or more language academies or official language bodies. However, the degree of control that the academies exert over these languages does not render the latter controlled natural languages in the sense that the various kinds of "simple English" (e.g. Basic English, Simplified Technical English) or George Orwell's fictional Newspeak are. They instead remain natural languages to a considerable extent and are thus not formal languages such as Attempto Controlled English. They have a degree of standardization that allows them to function as standard languages (e.g. standard French). The English language has never had a formal regulator anywhere, outside of private productions such as the Oxford Dictionary.

Apart from the Akademio de Esperanto, most constructed languages (also called conlangs) have no true linguistic regulators or language academies.^[22]

These bodies do not attempt to regulate any language in a prescriptive manner and are primarily concerned with aiding and advising the government on policies regarding language usage.
