The Thuringian-Franconian Highlands (German: Thüringisch-Fränkische Mittelgebirge) are a natural region of Germany which is designated as D48 or 39 by the BfN. It consists mainly of a ridge of mountains up to just under 1,000 m high between the Central Upland areas of the Thuringian Forest, Thuringian Slate Mountains, Franconian Forest and Fichtel Mountains, and which runs from west and south Thuringia through Upper Franconia and southeast to just before the Czech border and the so-called Bohemian Massif.
