Judeo-Hamadani and Judeo-Borujerdi constitute a Northwestern Iranian language, originally spoken by the Iranian Jews of Hamadan and Borujerd in western Iran. Hamadanis refer to their language as ebri "Hebrew" or zabān-e qadim "old language". Though not Hebrew, the term ebri is used to distinguish Judeo-Hamadani from Persian.

In western Iran, the district of Hamadan is split between Tuyserkan, Malayer, and Nahavand. This district along with Borujerd, further south in Lorestan Province, forms a geographic cluster that was inhabited by a good portion of Iranian-Jewish communities until recently when those communities emigrated to Tehran, Israel, and North America. Already in 1701, Paul Lucas (cited by De Planhol 2003) wrote that Jews were more numerous in Hamadan than elsewhere in Persia. According to Encyclopedia Iranica, the Jewish community had dwindled from around 13,000 souls in 1920 to less than 1,000 by 1969.
