The Franconian Circle () was an Imperial Circle established in 1500 in the centre of the Holy Roman Empire. It comprised the eastern part of the former Franconian stem duchy—roughly corresponding with the present-day Bavarian "Regierungsbezirke" of Upper, Middle and Lower Franconia—while western Rhenish Franconia belonged to the Upper Rhenish Circle. The title of a "Duke of Franconia" was claimed by the Würzburg bishops.
