Eliyahu Ben Chaim (born August 4, 1940) is a Sephardi rabbi, Talmudic scholar, and Orthodox halachist.

In Tehran, Ben Haim began serving the local community of Mashadi Jews as a rabbi and hazzan.

In 1979, in the wake of the Iranian Revolution, he went with his family to the United States and served as the chief rabbi of the Mashadi Persian Jewish community of Long Island (UMJCA).

Ben Haim was considered a close friend of Mordechai Eliyahu and delivered many eulogies for him.

Rabbi Ben Haim, like his teacher, Ovadia Yosef, advocates using the Kochah DeHeterah (power of leniency) to assist every Jew in need, especially agunot, women whose husbands refuse to provide a get (Jewish bill of divorce).
