Emmendingen (German: Landkreis Emmendingen) is a Landkreis (district) in the west of Baden-Württemberg, Germany. Neighbouring districts are (from north clockwise) Ortenaukreis , Schwarzwald-Baar, Breisgau-Hochschwarzwald and the district-free city Freiburg. To the west it borders the French département Bas-Rhin.

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 Ortenaukreis instead.
