The Jews of Kurdistan are the Mizrahi Jewish communities native to the geographic region of Kurdistan, roughly covering parts of northwestern Iran, northern Iraq, northeastern Syria and southeastern Turkey. Kurdish Jews lived as closed ethnic communities until they were expelled from Arab and Muslim states from the 1940s–1950s onward. The community largely speaks Judeo-Aramaic and Kurdish languages, with the Kurmanji dialect of Iraqi Kurdistan being the most prevalent. As Kurdish Jews natively adhere to Judaism and originate from the Middle East, Mizrahi Hebrew is used for liturgy. Many Kurdish Jews, especially the ones who hail from Iraq, went through a Sephardic Jewish blending during the 18th century. In the present-day, the overwhelming majority of Kurdistan's Jewish population resides in the State of Israel, with the community's presence coming as a direct result of either the Jewish exodus from Muslim states or the making of Aliyah by stragglers in the following decades (see Kurdish Jews in Israel).

These travellers also report of well-established and wealthy Jewish communities in Mosul, which was the commercial and spiritual center of Kurdistan. Many Jews fearful of approaching crusaders, had fled from Syria and Palestine to Babylonia and Kurdistan. The Jews of Mosul enjoyed some degree of autonomy in managing their own community. Ottoman era Tanna'it Asenath Barzani, who lived in Mosul from 1590 to 1670, was the daughter of Rabbi Samuel Barzani of Kurdistan. She later married Jacob Mizrahi Rabbi of Amadiyah (in Iraqi Kurdistan) who lectured at a yeshiva. She was famous for her knowledge of the Torah, Talmud, Kabbalah and Jewish law. After the early death of her husband, she became the head of the yeshiva at Amadiyah, and eventually was recognized as the chief instructor of Torah in Kurdistan. She was called tanna'it (female Talmudic scholar), practiced mysticism, and was reputed to have known the secret names of God. Asenath is also well known for her poetry and excellent command of the Hebrew language. She wrote a long poem of lament and petition in the traditional rhymed
