Armenia is subdivided into eleven administrative divisions. Of these, ten are provinces, known as marzer or in the singular form marz in Armenian.

Yerevan is treated separately and granted special administrative status as the country's capital. The chief executive in each of 10 marzes is the marzpet, appointed by the government of Armenia. In Yerevan, the chief executive is the mayor, appointed by the president.

The following is a list of the provinces with population, area, and density information. Figures are from the National Statistical Service of the Republic of Armenia.

Note that the area of the Gegharkunik Province includes Lake Sevan which covers 1,278 square kilometers (493.4 sq mi) of its territory.

Within each province are communities (hamaynkner, singular hamaynk). Each community is self-governing and consists of one or more settlements (bnakavayrer, singular bnakavayr).

Settlements are classified as either towns (kaghakner, singular kaghak) or villages (gyugher, singular gyugh). As of 2007, Armenia includes 915 communities, of which 49 are considered urban and 866 are considered rural.

The capital, Yerevan, also has the status of a community. Additionally, Yerevan is divided into twelve semi-autonomous districts.
