Yeshayahu Hadari (Hebrew: ישעיהו הדרי, 1933 – April 25, 2018) was an Israeli rabbi.

He served as the first rosh yeshiva of Yeshivat HaKotel,[1][2][3] a position he held for over thirty years.

After waking from an extended coma, the name Chaim (meaning "life") was added to his name to signify his survival of a near-death experience.

In 1962, Hadari was appointed mashgiach ruchani at Yeshivat Kerem B'Yavneh, where he worked for three years.

In 1967, Hadari was appointed to head the prestigious Yeshivat HaKotel in the Jewish Quarter of the Old City of Jerusalem.
