Eliezer Livneh (Hebrew: אליעזר ליבנה (born 2 December 1902, died 1 March 1975) was a Zionist activist, journalist, publicist and Israeli politician.

[2] Eliezer Liebenstein (later Livneh) was born in Łódź in the Russian Empire (now Poland) in 1902,[3] but his family moved to Rostov-on-Don at the outbreak of World War I.

[4] His experiences of the Nazi rise to power made him an opponent of totalitarian regimes of any kind, including that of Joseph Stalin, which was popular among many in the proletarian movement.

Edited by Livneh, it became the voice of the "activist" faction of Mapai for seven years until it went too far by publishing an obituary listing the names of Dov Gruner, Yehiel Drezner and Eliezer Kashani—Irgun members who became Olei Hagardom in April 1947—alongside Haganah casualties who were killed during the illegal immigration activities.

He was among the activist members of the party, taking an ardent pro-American stand in the struggle against Mapam, regarding Israel's relation with the United States and the Soviet Union.

[10] Before the elections to the third Knesset, he was reported to have purchased a relatively luxurious apartment in Kiryat Hayovel, Jerusalem, and was scolded by his party for deviating from the modest behavior policy.

Supporters of Israel's nuclear plan, headed by Ben-Gurion along with Shimon Peres and Ernst David Bergmann, acted behind the scenes to promote the program.

According to Avner Cohen, its term of operation was the closest thing in Israeli history to public democratic debate on nuclear policy.
