Isidore "Dore" Gold (Hebrew: איזידור "דורי" גולד‎; 25 July 1953 – 3 March 2025) was an American-born Israeli political scientist and diplomat.

After making aliyah in 1980, Gold worked at the research institutes Moshe Dayan Center for Near East Studies and the Jaffee Centre for Strategic Studies, before serving as Prime Minister Benjamin Netanyahu's Foreign Policy Advisor from 1996 to 1997. He then was appointed Permanent Representative of Israel to the United Nations, and served in the post until 1999.

Gold was the president of think tank Jerusalem Center for Public Affairs from 2000 to 2022, including an appointment as Director-General of the Israeli Ministry of Foreign Affairs from May 2015 to October 2016.

Dore Gold was born on 25 July 1953 in Hartford, Connecticut, United States, and was raised in a Conservative Jewish home. His primary education was spent at the Orthodox Yeshiva of Hartford. In the 1970s, Gold attended Northfield Mount Hermon School (Class of 1971) and then enrolled in Columbia University. There Gold earned BA and MA degrees in Political Science, and then a PhD in Political Science and Middle Eastern Studies.

Gold studied literary Arabic and specialized in international law, and his doctoral dissertation was about Saudi Arabia. This research later formed the foundation for his 2003 New York Times bestseller, Hatred's Kingdom: How Saudi Arabia Supports the New Global Terrorism. In the book, Gold argued that Saudi Arabia was actively funding terrorism by supporting the enemies of the U.S. and attacking its allies.

Gold made aliyah to Israel in 1980.

Gold's career began in 1985 when he served as senior research associate at Tel Aviv University's Moshe Dayan Center for Near East Studies. Later, he was appointed Director of the U.S. Foreign and Defense Policy Project at the Jaffee Centre for Strategic Studies at Tel Aviv University and held this position from 1985 to 1996.

In 1991, Gold was an advisor to the Israeli delegation at the Madrid Peace Conference.
