The
Regierungsbezirk Weser-Ems was the most westerly of the four administrative regions of
Lower Saxony,
Germany, bordering on the
Dutch provinces of
Groningen,
Drenthe and
Overijssel. It was established in 1978 by merging the former regions Osnabrück, Aurich, and Oldenburg. It was formally dissolved by the end of 2004 along with the other
Regierungsbezirke of Lower Saxony as part of an effort to optimize the administrative system of the state.
