Macedonia (Greece)
Macedonia (; , "Makedonía" ) is a geographic and former administrative region of Greece, in the southern Balkans. Macedonia is the largest and Greek region, with a population of 2.38 million in 2017. The region is highly mountainous, with most major urban centres such as Thessaloniki and Kavala being concentrated on its southern coastline. Together with Thrace, and sometimes also Thessaly and Epirus, it is part of Northern Greece. It also contains Mount Athos, an autonomous monastic region of Greece.
Aegean Macedonia
"Aegean Macedonia" (, ) is the Greek region of Macedonia in Northern Greece. It is currently mainly used in the Republic of Macedonia, including in the irredentist context of a United Macedonia. The term is also used in Bulgaria as the more common synonym for Greek Macedonia, without the connotations it has in the Republic of Macedonia. The term has no circulation in Greece, since "Aegean" usually refers to the Greek islands or to strictly Greek coastal areas with direct access to the Aegean Sea. Although Greek Macedonia does indeed have its coastline along the northern Aegean, the province is more than anything else dominated by its high mountain ranges and broad, grassy plains, rather than by its coastline (with the exception of the Chalkidiki peninsula, which is a popular holiday destination in eastern Macedonia noted for its beaches).
