Dov Weissglas (Hebrew: דב ויסגלס; born 4 October 1946) is an Israeli lawyer and businessman who was involved in the Middle East peace process during the term of Prime Minister Ariel Sharon.

After graduating from the Ohel Shem high school, he served in the Israel Defense Forces and began studying law at the Hebrew University of Jerusalem at age 19.

His clients included Yitzhak Rabin, Ariel Sharon, Ehud Olmert, Yisrael Meir Lau, Avigdor Lieberman, and Effie Eitam.

He represented two Shin Bet officers tasked with monitoring Jewish extremists before the Shamgar Commission, two Mossad agents captured in Jordan during a failed operation to assassinate Khalid Mashal, the locomotive driver in the HaBonim disaster, the chairman of the organizing committee of the Maccabiah Games in the aftermath of the Maccabiah bridge collapse, and Rafi Eitan before the US authorities in the Jonathan Pollard affair.

In this role, he served as a diplomatic delegate for negotiating with U.S. National Security Advisor Condoleezza Rice and U.S. Secretary of State Colin Powell, and was one of the key architects of the Israeli disengagement from Gaza.
