Beitar Illit is a Haredi Jewish-Israeli settlement organized as a city council in the Gush Etzion settlement bloc, ten kilometres (6 mi) southwest of Jerusalem in the West Bank. Beitar Illit is one of Israel's largest and most rapidly growing settlements, and in 2022 had a population of 64,016.

Haredi Judaism consists of groups within Orthodox Judaism that are characterized by their strict interpretation of religious sources and their accepted halakha and traditions, in opposition to more accommodating or modern values and practices. Its members are usually referred to as ultra-Orthodox in English; however, the term "ultra-Orthodox" is considered pejorative by many of its adherents, who prefer terms like strictly Orthodox or Haredi. Haredi Jews regard themselves as the most religiously authentic group of Jews, although other movements of Judaism disagree.
