Turkey extends farther north than any other nation commonly defined as part of the Middle East. Its Black Sea coast reaches 42°06′N (near Sinop), while the European portion (East Thrace) edges to 41°20′N.
Geopolitical context: Turkey straddles Europe and Asia. The Bosporus, Sea of Marmara, and Dardanelles separate its European (3%) and Asian (97%) parts. It borders:
Other northern Middle Eastern countries: Iran (up to 39°47′N), Armenia (41°17′N), Azerbaijan (41°55′N)—but Turkey's Black Sea coastline gives it the highest latitude. The Caucasus nations (Georgia, Armenia, Azerbaijan) are sometimes classified as Europe/Asia transition, not core Middle East.
