A municipiu (from Latin municipium; English: municipality) is a level of administrative subdivision in Romania and Moldova, roughly equivalent to city in some English-speaking countries.
There is no clear benchmark regarding the status of municipiu even though it applies to localities which have a sizeable population, usually above 15,000, and extensive urban infrastructure.
Localities that do not meet these loose guidelines are classified only as towns (orașe), or if they are not urban areas, as communes (comune).
In Moldova, which has thirteen municipii, a 2002 law provides that the status applies to the cities that play an important role in the country's economic, social, cultural, scientific, political and administrative life.
Cluj and Oradea temporarily lost the title in 1940 as a result of the Second Vienna Award, while it was granted to Odessa and Tiraspol during the Transnistria Governorate period.
