Destroyed bridge over the Yarmouk River
The Yarmuk River, sometimes also spelled "Yarmouk" (Arabic: نهر اليرموك, "Nahr Al-Yarmuk"; Hebrew: נהר הירמוך, "Nahar HaYarmukh"; Greek: Hieromax; Latin: Hieromyces) is the largest tributary of the Jordan River. It drains much of the Hauran plateau. It is one of three main tributaries which enter the Jordan between the Sea of Galilee and the Dead Sea. To the south are the Zarqa River and the Wadi Mujib rivers.
Yarmuk forms the border between Israel and Jordan close to the Jordan Valley and between Syria and Jordan further upstream. It is the southern boundary of the Golan Heights.
The Battle of Yarmouk, where Muslim forces defeated those of the Byzantine Empire and gained control of Syria, took place south of the river in 636.
