The Jaghjagh River (Arabic: نهر جقجق Nahr Jaqjaq, نهر الجغجغ Nahr al-Jaghjagh, or Nahr al-Hirmas, Turkish: Çağ-çağ Deresi, Kurdish: Çemê Nisêbînê or Cexcex) is a tributary of the Khabur River in Turkey and Syria.
The river has two sources. The longer branch, known as Siyahsu (meaning dark water, Kurdish Av-e Resh), rises near the village of Toptepe in Mardin Province, Turkey, and flows 10 km to the confluence with the shorter branch, known as Beyazsu (meaning white water, Kurdish Av-e Spi).
