Nahal Gerar, also Nachal Grar (Hebrew: נחל גרר) is a wadi in Israel, in the Negev desert. Its Arabic name is Wadi esh-Sheri'a (also Wady el Sharia and other variations).[1] Along this wadi, there are several important ancient Bronze Age archaeological sites. During the Early Iron Age this was an area of Philistine settlement.
