Nomes ( prefectures ; Greek νομοί , unit part νομός ) - abolished (from January 1, 2011 according to the Kallikratis Program ) administrative units of the second level of Greece . As a result of the reforms, the nomes became peripheral units ( Greek περιφερειακές ενότητες ) as part of the peripheries (administrative regions); the borders of peripheral units basically, but not always, coincide with the borders of nomes.

Below are listed all the nomes (prefectures) of Greece by their location in the administrative districts and according to the numbering on the map.
