Joseph ben Hayyim Jabez (also "Yaavetz") (1438-1539) was a Spanish-Jewish theologian. He lived for a time in Portugal, where he associated with Joseph Hayyun, who inspired him with that taste for mysticism which he subsequently displayed in his writings. When the Jews were banished from Spain Jabez settled at Mantua, Italy. There he met his compatriot, the kabbalist Judah Hayyat, whom he induced to write the commentary Minḥat Yehudah on the kabbalistic work Ma'areket Elahut.
