Northern Bavarian Northern Bavarian is a dialect of the Bavarian language, together with Central Bavarian and Southern Bavarian. The language is mostly spoken in the Upper Palatinate, although not in Regensburg, which is a primarily Central Bavarian–speaking area, according to a linguistic survey done in the late 1980s. According to the same survey, Northern Bavarian is also spoken in Upper Franconia, as well as in some areas in Upper and Lower Bavaria, such as in the areas around Eichstätt and Kelheim. Few speakers remained in the Czech Republic, mostly concentrated around Aš and Železná Ruda, at the time of the survey, but considering the time which has passed since the survey, the dialect may be extinct in those places today. If it still exists there, it would include the "ostegerländische Dialektgruppe". Ethnologue states that there are 9,000 speakers of the Bavarian language as of 2005 in the Czech Republic, but doesn't state how many of these are speakers of Northern Bavarian.
