a portion of southeastern Turkey is considered part of the broader Upper Mesopotamia region, specifically the areas encompassing the headwaters and upper valleys of the Tigris and Euphrates rivers.
However, Turkey's major modern maritime ports (such as Istanbul, İzmir, Mersin, or Samsun) lie outside of Mesopotamia along the Mediterranean, Aegean, Black Sea, or Sea of Marmara coasts.
• Southeastern Anatolia (Upper Mesopotamia): The southeastern provinces of Turkey—including Şanlıurfa, Mardin, Diyarbakır, and Adıyaman—are part of the historical Mesopotamian watershed.
• Inland Rivers: Historically, river transport or trading ports existed along the upper Euphrates (such as the ancient city of Samsat in Adıyaman), though these were river ports rather than sea ports connected to international maritime trade.
• Modern Maritime Ports: Turkey's active commercial and industrial sea ports (like İskenderun and Mersin on the Mediterranean) sit on the Mediterranean coast outside the geographical basin of Mesopotamia proper.
土耳其东南部的一部分被视为广义“上美索不达米亚”地区的一部分，具体而言，即涵盖底格里斯河与幼发拉底河源头及上游河谷的区域。
然而，土耳其主要的现代海港（如伊斯坦布尔、伊兹密尔、梅尔辛或萨姆松）并不位于美索不达米亚境内，而是分布在地中海、爱琴海、黑海或马尔马拉海沿岸。
• 安纳托利亚东南部（上美索不达米亚）：土耳其东南部的各省——包括尚勒乌尔法、马尔丁、迪亚巴克尔和阿德亚曼——均属于历史上美索不达米亚流域的一部分。
• 内陆河流：历史上，在幼发拉底河上游曾存在过河运设施或贸易港口（例如位于阿德亚曼的古城萨姆萨特），但这些属于内河港口，而非与国际海上贸易相连的海港。
• 现代海港：土耳其活跃的商业与工业海港（如位于地中海沿岸的伊斯肯德伦和梅尔辛）均坐落于地中海沿岸，处于美索不达米亚地理盆地范围之外。
