Baghdad Jewish Arabic: Baghdad Jewish Arabic is the Arabic dialect spoken by the Jews of Baghdad and other towns of Southern Iraq.  This dialect differs from the dialect spoken by the Jews in Northern Iraq, such as Mosul and 'Ana.  The Baghdadi and Northern dialects may be regarded as subvarieties of Judeo-Iraqi Arabic.  As with most Judeo-Arab communities, there are likely to be few, if any, speakers of the Judeo-Iraqi Arabic dialects who still reside within Iraq.  Rather these dialects have been maintained or are facing critical endangerment within respective Judeo-Iraqi diasporas, namely those of Israel and the United States.  In 2014, the film "Farewell Baghdad" (Arabic: مطير الحمام; Hebrew: מפריח היונים, lit.  "The Dove Flyer"), which is performed mostly in Jewish Baghdadi Arabic dialect, became the first film to be almost completely performed in Judeo-Iraqi Arabic.
