Rabbi Yitzhak Haim Peretz (Hebrew: יצחק חיים פרץ, born 26 March 1938) is a former Israeli politician who held several ministerial portfolios during the 1980s and early 1990s.

In 1984, Peretz became the leader of the new Sephardic Haredi Shas party,[1] and in the elections that year, he won a seat in the Knesset.

On 24 December 1984, he became Minister of Internal Affairs, a post he resigned two years later, in January 1987, in protest against the Supreme Court ordering him to recognise as Jewish a woman who underwent a conversion to Judaism with a Reform rabbi, a controversial procedure from the Haredi point of view, stating that "The High Court of Justice demanded that I list a non-Jew as a Jew".

Prior to the 1992 elections, he joined United Torah Judaism (UTJ), and was placed second on the party's list, in order to attract voters from Shas, with the agreement that he would resign from the Knesset if his presence did not significantly increase the alliance's vote share.

The elections saw UTJ win only three seats, a reduction from the seven won by the two parties running separately in 1988, and Peretz resigned three days after the Knesset term started.
