Yaaqov Medan (spelled Yaakov or Ya'acov) (Hebrew: יעקב מדן) (born 1950) is an Israeli Orthodox rabbi, co-Rosh yeshiva of Yeshivat Har Etzion, a respected leader in the Religious-Zionist community, and a lecturer in Tanakh, Gemara, and Jewish philosophy.

He served in the Airborne Nahal Infantry unit during his Hesder army service.

During the Yom Kippur War, he fought in the Golan Heights as a liaison officer in the Yiftach Brigade.

A much wider variety of lectures which he has given at Yeshivat Har Etzion have not yet been published in written form.

He was a partner in drafting the Gavison-Medan Covenant,[6][7] a proposed constitution for the State of Israel which is intended to benefit Israel's religious and secular communities simultaneously (despite their disagreement on a number of issues).
