Baruch Kopel Goldstein was an American-Israeli mass murderer, religious extremist, and physician who perpetrated the 1994 Cave of the Patriarchs massacre in Hebron in the Israeli-occupied West Bank, an incident of Jewish terrorism. Goldstein was a supporter of the Kach, a religious Zionist party that the United States, the European Union and other countries designate as a terrorist organization.

The Cave of the Patriarchs massacre, also known as the Ibrahimi Mosque massacre or the Hebron massacre, was a shooting massacre carried out by Baruch Goldstein, an American-Israeli physician and extremist of the far-right ultra-Zionist Kach movement. On 25 February 1994, during the Jewish holiday of Purim, which had overlapped in that year with the Islamic holy month of Ramadan, Goldstein opened fire with an assault rifle on a large gathering of Palestinian Muslims praying in the Ibrahimi Mosque in Hebron. He killed 29 people, several as young as 12 years, and wounded 125. Goldstein was overpowered and beaten to death by survivors.
