The Yarmuk River (Arabic: نهر اليرموك‎‎, Nahr Al-Yarmuk, or شريعة المناذرة, Shariat el Menadhirah; Hebrew: נהר הירמוך‎‎, Nahar HaYarmukh; Latin: Hieromices), sometimes spelled Yarmouk, is the largest tributary of the Jordan River. It runs in Jordan, Syria, and Israel and drains much of the Hauran plateau. Its main tributaries are the wadis of 'Allan and Ruqqad from the north, Ehreir and Zeizun from the east. Although it is narrow and shallow throughout its course, at its mouth it is nearly as wide as the Jordan, measuring thirty feet in breadth and five in depth. The once celebrated Matthew Bridge used to cross the Yarmuk at its confluence with the Jordan.
