Bayreuth (German pronunciation: [baɪˈʁɔʏt] ⓘ) is a Landkreis (district) in Bavaria, Germany.

The district is bounded by (from the north and clockwise) the districts of Kulmbach, Hof, Wunsiedel, Tirschenreuth, Neustadt an der Waldnaab, Amberg-Sulzbach, Nürnberger Land, Forchheim and Bamberg.

The valley of the Red Main separates the two major geographical regions of the district from each other: the hilly countryside of the Franconian Jura and the much higher Fichtel Mountains.

Within the county lies the Veldenstein Forest, one of the largest contiguous areas of woodland in Bavaria.

The arms display the heraldic eagle of the Hohenzollern dynasty together with the white and blue pattern of Bavaria.
