Naomi Blumenthal (Hebrew: נעמי בלומנטל, born 22 November 1943) is a former Israeli politician.

Born in Bitzaron during the Mandate era, Blumenthal served in a Nahal brigade during her national service.

She gained a BA in Political Science and Criminology from Bar-Ilan University and also graduated from the Beit Zvi School of Art in Ramat Gan.

Although re-elected in 2003, it later emerged that she had bribed 15 Likud activists and central committee members during the party primaries in December 2003 by hosting them in a hotel in Ramat Gan.

However, in July 2007 President Shimon Peres commuted her sentence to community service,[4] though she was not pardoned.
