Aryeh Ben-Eliezer (Hebrew: אריה בן אליעזר, 16 December 1913 – 29 January 1970) was a Revisionist Zionist leader, Irgun member and Israeli politician.

He was acting leader of Herut from August 1951, after Menachem Begin resigned as a result of the 1951 Israeli legislative election, until January 1952, when Ben-Eliezer's heart attack the previous month and the debate over the Reparations Agreement between Israel and the Federal Republic of Germany prompted Begin's return to political activity.

After the outbreak of World War II, he was sent on an Irgun mission to the United States and helped to found the Committee for the Creation of a Hebrew Army.

He was one of the first to propose a referendum as a proviso for crucial decisions, as part of his party's opposition to the Reparations Agreement between Israel and West Germany.

When Begin again announced his intention to resign as Herut chairman in 1966 after the party's disappointing result in the 1965 Israeli legislative election, Ben-Eliezer was a candidate to succeed him along with Shmuel Tamir.
