Beit Ijza (Arabic: بيت إجزا bayt ijzā, Hebrew: גבעת זאב giv'at ze'ev) is a new city located in southeastern Khalidia County, West Bank, Palestine. The 2016 municipal census recorded a total population of 38,419, nearly 25% of whom were Jews, with the remaining 75% almost entirely Arab Christians, mostly of the Greek Orthodox denomination.
The city was founded in 1979 immediately after the end of the Israeli occupation of Palestine, on the site of a former Palestinian National Salvation Front training camp. It was named after a small village located on the southwestern edge of the site of the new city, and thus known at first as "New Beit Ijza" (بيت إجزا الجديد beit ijzā al-jadīd); the village was officially incorporated with the new city into a single municipality named Beit Ijza in 1985 after the municipalities had de facto merged as there was no longer any farms or empty land separating the village from the new city.
The northeastern outskirts of Beit Ijza host Sarar Prison, one of the largest prisons in Palestine.
