Rivers Originating in Turkey & Flowing Through Iraq: Tigris & Euphrates

Two historic rivers rise in eastern Turkey and traverse Iraq, defining Mesopotamia — the "Land Between the Rivers."

Tigris River (Dicle)

• Source: Lake Hazar / Taurus Mountains, eastern Turkey
• Course: SE through Turkey (Diyarbakır) → Iraq (Mosul, Baghdad) → joins Euphrates at Al-Qurnah → Shatt al-Arab → Persian Gulf
• Length: ~1,850 km (1,150 mi)

Euphrates River (Fırat)

• Source: Murat & Karasu rivers confluence, Armenian Highlands, eastern Turkey
• Course: SE through Turkey ( Atatürk Dam) → Syria → Iraq (Fallujah, Ramadi, Najaf) → joins Tigris
• Length: ~2,800 km (1,740 mi) — longer but less discharge than Tigris

Civilizational Role

Sumer, Akkad, Babylon, Assyria flourished on their waters. Modern Iraq depends on them for agriculture, drinking water, marshland restoration (Mesopotamian Marshes), and hydropower. Transboundary water sharing (Turkey–Syria–Iraq) remains a critical geopolitical issue.
