Moshe Erem (Hebrew: משה ארם, 7 August 1896 – 14 October 1978) was an Israeli politician who served as a member of the Knesset for several left-wing parties and factions from 1949 until 1959, and again from 1965 until 1969.

Born Moshe Kazanovski in Lyady in the Russian Empire (now in Belarus), Erem worked as a high school headteacher in Kaunas.

He retained his seat in the 1951 elections, but on 23 August 1954, left the party alongside Israel Bar-Yehuda, Yitzhak Ben-Aharon and Aharon Zisling to re-establish Ahdut HaAvoda - Poale Zion as an independent party.

He failed to win a seat in the 1961 elections, but entered the Knesset on 4 May 1965 as a replacement for the deceased Bar-Yehuda.

[2] He retained his seat in the November 1965 elections, by which time Ahdut HaAvoda had entered an alliance with Mapai, known as the Alignment.
