מארי יחיא בן יוסף צאלח, היה מגדולי חכמי יהדות תימן במאה ה-18, וראב"ד בבית הדין הגדול בצנעא.
Rabbi Yiḥya Ṣāleḥ, known by the acronym of Maharitz, , was one of the greatest exponents of Jewish law known to Yemen. He is the author of a liturgical commentary entitled Etz Ḥayyim, in which he follows closely the legal dicta of Maimonides. Rabbi Yiḥya Ṣāleḥ is widely remembered for his ardent work in preserving Yemenite Jewish customs and traditions, which he articulated so well in his many writings, but also for his adopting certain Spanish rites and liturgies that had already become popular in Yemen. In this regard, he was strongly influenced by the Rabbis of his previous generation, Rabbi Yehudah Sa'adi and Rabbi Yihya al-Bashiri. Initially, Rabbi Yiḥya Ṣāleḥ worked as a blacksmith until the age of thirty, after which he worked as a scrivener of sacred texts, before becoming chief jurist of the rabbinical court in Sana'a.
