Municipal okrug

Okrug (Bulgarian: окръг, okrǎg, Russian: о́круг; Serbian: округ, IPA: [ôkruːɡ]; Ukrainian: окру́га, okruha; Belarusian: акруга, Akruha; Polish: okręg; Abkhazian: оқрҿс; Meadow Mari: йырвел, jyrvel) is an administrative division of some Slavic states. The word "okrug" is a loanword in English, but it is nevertheless often translated as "area", "district", or "region".

In meaning, the word is similar to the German term Bezirk ("district") and the French word Arrondissement; all of which refer to something "encircled" or "surrounded".

In Bulgaria, okrаgs are the abolished primary unit of the administrative division and implied "districts" or "counties". They existed in the post-War Bulgaria between 1946 and 1987 and corresponded approximately to today's oblasts.

As historical administrative subdivisions of Poland, okręgi existed in the later part of the Congress Poland period, from 1842, when the name was applied to the former powiats (the name powiat being transferred to the former obwody). See Administrative division of Congress Poland.
