Bad Berneck im Fichtelgebirge (German: [baːt ˈbɛʁnɛk] ⓘ) is a spa town in the district of Bayreuth, in Bavaria, Germany.

Bad Berneck's neighbouring parishes (in clockwise order) are: Gefrees, Goldkronach, Bindlach, Harsdorf, Himmelkron and Marktschorgast.

The exact date of Bad Berneck's foundation is not known, but up to 1057 the place was under the control of the lords of Babenberg and later the counts of Andechs.

In 1248, following the extinction of House of Merania, it fell to the counts of Orlamünde and in 1341 to the burgraves of Nuremberg (and, later, the margraves of Brandenburg-Bayreuth).

In 1478 the Marquis gave Berneck to Veit von Wallenroth with the stipulation that the fortifications were to be rebuilt.

In 1732 Margrave George Frederick Charles of Brandenburg-Bayreuth had pearl oysters introduced into the Ölschnitz, probably to supplement the state's finances In the wars of 1796-1815 the small town had to pay several contributions and provide billeting.

The former office (Amt) of the Prussian principality of Bayreuth, established since 1792, fell to France in 1807 as a result of the Treaty of Tilsit and, in 1810, went to Bavaria.

Within Bavaria, Berneck was initially the seat of a regional court (Landgericht), later a district office (Bezirksamt).

In the 1930s, Adolf Hitler spent the night in the then fashionable Bube Hotel on several occasions during the festival in Bayreuth.

Bad Berneck lies at the intersection of B 2 (Hof - Bayreuth) and B 303 (Kronach - Eger) federal highways.
