Yaakov Amidror (Hebrew: יעקב עמידרור; born 15 May 1948) is a former major general and National Security Advisor of Israel and was also the head of the Research Department of Israeli military intelligence.

His mother, Tzila, was an Irgun member, active in the organization's finance department, who had been arrested by the British in 1941, and incarcerated at the Bethlehem Women's Prison.

Amidror was considered a candidate to lead the Military Intelligence Directorate, but he was passed over after he controversially referred to non-religious Israelis as "Hebrew-speaking gentiles".

As Israel's national security advisor, he participated in high-level talks with U.S. officials about the Iranian nuclear program and led efforts to restore relations with Turkey after the Gaza flotilla raid incident.

In 2016, Amidror chaired an official panel charged with providing recommendations to improve the functioning of Israel's National Security Council and cabinet ministers during wartime.
