The murder of Ori Ansbacher (Hebrew: רצח אוֹרי אַנְסְבַּכֶר, also known as the Ein Yael attack) was a terror attack on 7 February 2019 during which a Palestinian man raped and then murdered Ori Ansbacher, a 19-year-old Israeli woman from Tekoa.

On February 7, 2019 (2019-02-07), 11:00 AM, Ori's relatives reported her absence to the police. Ori volunteered at a youth center in Jerusalem and, according to friends, on the same day she had left the center agitated and went to seclude herself in nature, as she often liked to do. On 19:14 PM that day, her lifeless body was found by the police in the Ein Yael forest in the outskirts of Jerusalem, with signs of harsh violence. On February 8, 2019 (2019-02-08), a suspect for the murder named Arafat Irafaiya was arrested by the Israeli security forces in Ramallah. Irafaiya had a terrorist background and had spent time in an Israeli prison before the attack. He and his family are affiliated with Hamas. Irafaiya admitted to raping and murdering Ori, saying that the attack wasn't planned aside from his purchasing of a kippa so that he could enter Israel undetected, adding "I entered Israel with a knife because I wanted to become a martyr and murder a Jew, I met the girl by chance”.

Irfaiya, who was deemed fit to stand trial, pleaded guilty at the Jerusalem District Court to charges of first-degree murder with a terror motivation, rape and illegal entry into Israel.

The murder and its gruesome details caused fury among the Israeli public. Rumors circulating that Ori was decapitated by the murderer caused the Israeli police to release an official statement denying such claims.

The murder drove the Israeli government to act on the issue of imprisoned Palestinian terrorists receiving monthly stipends from the Palestinian Authority. On February 17, 2019 (2019-02-17), the Israeli security cabinet decided to enforce earlier legislation intended to deduct from money delivered by Israel to the Palestinian Authority the amount the Palestinian Authority pays to imprisoned terrorists, sparking outrage among Palestinian officials. Two of Irafaiya's family homes were later demolished by security forces.

Militant Palestinian groups, including Hamas and Islamic Jihad, condemned the killing after it was revealed that Ansbacher had been raped before her murder. Irfaiya received no legal representation from Palestinian Prisoners Club or other supporting groups. A senior Fatah official imprisoned in Israel also condemned the murder, expressing condolences to Ansbacher's family and asserting that there was nothing nationalist about Irfaiya's actions. He deemed the incident "an embarrassment to the Palestinian people" and stated that any attempt to place Irfaiya among Fatah prisoners would be resisted. Fatah had requested the Palestinian Authority not to provide Irfaiya with a monthly stipend or fund his defense.

The Jewish community in Gush Etzion planted dozens of trees in Ori's memory, which were later destroyed by Palestinian vandals.
