A raion (or rayon) (; Belarusian раён; Azeri: rayon, Latvian: rajons) is one of two kinds of administrative subdivisions in languages of some post-Soviet states: a subnational entity and a subdivision of a city. In these senses the term is almost always translated as "district".
Raion is a subnational entity of Azerbaijan, Belarus, Georgia, Latvia, Moldova, the Russian Federation, Ukraine, and the former Soviet Union. As an administrative subdivision, the term was introduced by the Soviet administrative reform of 1923–1929 that transformed many former volosts and uyezds of the Russian Empire into raions.
A raion is usually an entity two steps below the national level. It can be a subordinate part:
Typically, raions have some degree of self-governance in the form of a popularly elected district council (Raysovet) and the local head of administration, sometimes elected and sometimes appointed.
