Yitzhak Tabenkin (Hebrew: יצחק טבנקין‎, 8 January 1888 – 6 June 1971) was a Zionist activist and Israeli politician.

He was a member of the "Non-Party" workers group and was active in agricultural laborers organizations in what would later be called the West Bank.

He regarded the political borders of the Middle East following the partition of the Ottoman Empire as imposed by European imperialism.

[1] Moshav Yitav (a Hebrew acronym for "Yad Yitzhak Tabenkin") in the Jordan Valley is named after him.

He opposed the Peel Commission's recommendations and any of Ben-Gurion's attempts to reach a compromise with the Revisionist Zionists.

[4] In 1944 he led the "Bet" Faction that split from Mapai and created the new "Ahdut HaAvoda" party.

He said Israel's right to the Sinai Peninsula and the Gaza Strip was derived from the Ten Commandments and the blood of the soldiers killed in the war.

He considered the addition of over a million Arabs to Israel's population a problem that could be solved by a massive aliyah.
