East Franconian (German: Ostfränkisch [ˈɔstfʁɛŋkɪʃ] ⓘ), usually referred to as Franconian (Fränkisch [ˈfʁɛŋkɪʃ] ⓘ) in German, is a dialect spoken in Franconia, the northern part of the federal state of Bavaria and other areas in Germany around Nuremberg, Bamberg, Coburg, Würzburg, Hof, Bayreuth, Meiningen, Bad Mergentheim, and Crailsheim.

In the transitional area between Rhine Franconian in the northwest and the Austro-Bavarian dialects in the southeast, East Franconian has elements of Central German and Upper German.

East Franconian is one of the German dialects with the highest number of speakers.

The scope of East Franconian is disputed, because it overlaps with neighbouring dialects like Bavarian and Swabian in the south, Rhine Franconian in the west and Upper Saxon in the north.

East Franconian is researched by the "Fränkisches Wörterbuch" project in Fürth, which is run by Bayerische Akademie der Wissenschaften and Erlangen-Nuremberg University.
