The district dates back to the Bezirksamt Emmendingen, which was created in 1803 when the area became part of Baden. After several additions it was converted into the district Emmendingen in 1936, when it was merged with the Amt Waldkirch. In the communal reform of 1973 the district wasn't changed - at first it was planned to merge it with the district Lahr, but that was merged into the Ortenau District instead.
The western part of the district is located in the upper Rhine valley, including the small volcanic mountain Kaiserstuhl. This extinct volcano is one of the climatic best regions of Germany, with wine grapes growing on its sunny slopes. The eastern part of the district belongs to the Black Forest.
