Anatolia, also known as Asia Minor, is a large peninsula in West Asia and is the western-most extension of continental Asia. The land mass of Anatolia constitutes most of the territory of contemporary Turkey.
Geographically, the Anatolian region is bounded by the Turkish Straits to the north-west, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west.
Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus strait and the Dardanelles strait and separates Anatolia from Thrace in the Balkan peninsula of Southeastern Europe.
The eastern border of Anatolia is a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the south-east, thus Anatolia comprises approximately the western two-thirds of the Asian territory of Turkey.
Anatolia sometimes is synonymous with Asian Turkey, thereby including the western part of the Armenian Highlands and northern Mesopotamia and making its eastern and southern borders coterminous with Turkey's borders.
