Braunschweig (German Regierungsbezirk Braunschweig) was one of the eight former administrative regions (Regierungsbezirke) of Lower Saxony, Germany. It was located in the southeast of the state.
The region covers roughly the area of the former state of Brunswick-Lüneburg. It was founded in 1978 out of 'Verwaltungsbezirk Braunschweig'. At the end of 2004, all Regierungsbezirke of Lower Saxony were dissolved.
