Hayyim ben Isaac Raphael Alfandari (Hebrew: חיים בן יצחק אלפאנדארי; c. 1660–1733) was rabbi in Constantinople during the latter half of the 17th and in the beginning of the 18th century.

He was the author of Esh Dat (A Fiery Law), a collection of homilies printed together with his uncle's Muẓẓal me-Esh (Hebrew: מוצל מאש) in Constantinople, 1718.

Several short treatises by him are published in the works of others.

Azulai speaks very highly of him as a scholar and as a preacher.
