Sulzburg is a town in the district Breisgau-Hochschwarzwald, in Baden-Württemberg, Germany. It is situated on the western slope of the Black Forest, 20 km southwest of Freiburg.

Sulzburg had a long tradition of continuous Jewish settlement since medieval times. Around 1850, almost one third of its population of around 1,200 was Jewish. Sulzburg's lovely, barrel-vaulted synagogue has been completely restored. There exists an old Jewish cemetery near the town.
