Tzvia Greenfield (Hebrew: צביה גרינפילד; born 27 October 1945) is an Israeli politician and a former Member of the Knesset for Meretz.

In 1993, she established the Mifneh ["pivot point"] Institute to promote peace, tolerance, and democracy in Orthodox society.

She was one of the founders of Orthodox Women for the Sanctity of Life, which opposed the Israeli occupation of South Lebanon.

On 4 November 2008, Greenfield replaced Beilin, who retired from politics, and became the first Haredi woman sworn into the Knesset.

Greenfield opposes the Israeli occupation of Palestinian territories and supports a two-state solution to the Israeli–Palestinian conflict along the Green Line with "minor adjustments".
