A raion (or rayon) (Russian and Ukrainian: райо́н; Belarusian раён; Azeri: rayon, Latvian: rajons, Georgian: რაიონი, raioni) is one of two kinds of administrative subdivisions in languages of some post-Soviet states: a subnational entity and a subdivision of a city.
Raion is a subnational entity of Azerbaijan, Belarus, Georgia, Latvia, Moldova, the Russian Federation, Ukraine, and the former Soviet Union.
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.
