Idov Cohen (Hebrew: אידוב כהן, 4 November 1909 – 16 May 1998) was a Romanian-Israeli politician and journalist.

Between 1927 and 1933 he worked as a bookkeeper, before being appointed General Secretary of the Jewish National Fund in the country, a job he held until 1939.

In 1940 he made aliyah to Mandatory Palestine, where he was amongst the founders of the Association of Romanian Immigrants, and started work as the chief editor of The Zionist Worker.

He lost his seat in the July 1951 elections, but returned to the Knesset on 10 September as a replacement for Moshe Kol.

He was re-elected on the new party's list in elections later that year, but resigned from the Knesset on 11 November 1963, and was replaced by Aharon Goldstein.
