Nahal Iyyon (Hebrew: נחל עיון, lit. Iyyon Stream; Arabic: براغيث bureighith) is a perennial stream in the Galilee Panhandle, Israel. The stream originates from the springs in the Marjayoun valley in southern Lebanon, and runs southward for seven kilometers in various irrigation ditches, until flowing into Israel near Metulla, as a tributary of the Jordan River in the Hula Valley.
Differences in elevation form waterfalls in the streams course. During the rainy winter months, the water-flow is strongest. During the summer months, water is diverted, closer to the stream's sources, for crop irrigation. These falls were declared a nature reserve, and include:
- Iyyon waterfall, 9.2 m
- Tahana waterfall (=flourmill), 21 m
- Eshed waterfall, with two steps, 5 m and 9 m
- Tanur waterfall, 30 m
