Nahal Taninim (Hebrew: נחל תנינים‎‎, lit. Crocodile Stream) is a river in Israel, originating near Ramot Menashe and emptying into the Mediterranean Sea south of Ma'agan Michael. The Arabic name of the river is Wadi a-Zarka. The river is named for the crocodiles that inhabited the nearby Kebara swamps until the early 20th century. The remains of Crocodilopolis, a city established there in the fourth century BCE, are still visible today. The dense undergrowth and reeds along Nahal Taninim are home to many different birds, among them waterside warblers and other songbirds.
