Geographic regions of Greece

The traditional geographic regions of Greece (Greek: γεωγραφικά διαμερίσματα, lit.

'geographic departments') are the country's main historical-geographic regions, and were also official administrative regional subdivisions of Greece until the 1987 administrative reform.

[1] Despite their replacement as first-level administrative units by only partly identical administrative regions (Greek: περιφέρειες), the nine traditional geographic regions—six on the mainland and three island groups—are still widely referred to in unofficial contexts and in daily discourse.

As of 2011[update], the official administrative divisions of Greece consist of 13 regions (Greek: περιφέρειες)—nine on the mainland and four island groups—which are further subdivided into 74 regional units and 325 municipalities.

Formerly, there were also 54 prefectures or prefectural-level administrations.
