Yitzhak Moda'i (Hebrew: יצחק מודעי, 17 January 1926 – 14 May 1998) was an Israeli politician who served five terms in the Knesset for Likud and then the New Liberal Party over the course of a 20-year career.

His wife, Michal Har'el (née Herison), was Miss Israel, and then president of the Women's International Zionist Organization.

Their son, Boaz Moda'i, is a senior diplomat in the Israeli Ministry of Foreign Affairs, since October 2019 serving as Israel's ambassador to Slovakia.

[2] In December 1979 in his role as Energy Minister, Modai announced the Israeli government's intent to take over the Arab-run East Jerusalem Electric Company, which was viewed as one of the last existing symbols of Palestinian autonomy.

In 1985 he and Prime Minister Shimon Peres devised the economic stabilization plan that managed to curtail Israel's hyperinflation of the early 1980s.

[5] Due to the plan, the Israeli economy averted total collapse and inflation was reduced from an annual rate of almost 450% to less than 20% in less than two years.

During the dramatic and sometimes difficult process of economic stabilization, Moda'i became known for being brilliant, but was also perceived as volatile, autocratic and chronically obstreperous.
