Sulzbach-Rosenberg (Northern Bavarian: Suizboch-Rosnberg) is a municipality in the Amberg-Sulzbach district, in Bavaria, Germany.

The town consists of two parts: Sulzbach in the west, and Rosenberg in the east.

Archeological evidence tells that Sulzbach was an important centre from the 8th century on.

Sulzbach castle was founded during the early 8th century, probably by the late-Merovingian/early-Carolingian kingdom.

It is one of several locations that hosts the InterHarmony international Music Festival, first conceptualized in 1997.
