Breisgau-Hochschwarzwald (French: Arrondissement de Brisgau-Haute-Forêt-Noire) is a Landkreis (district) in the southwest of Baden-Württemberg, Germany.

Breisgau-Hochschwarzwald covers areas which are very different in scenic character: in the Upper Rhine Plain are the Markgräflerland and its foothill zone, which is continued north of the Breisgau with the hills of Kaiserstuhl, the Tuniberg and the Nimberg.

Within the district, the Black Forest covers the side valleys opening onto the Rhine Plain - the Glottertal, the valley of the Dreisam, the Höllental and the Münstertal - the High Black Forest with its highest peak, the Feldberg (1493 m), and extends as far as the plateau of Baar.

The neighbouring counties are Emmendingen, Schwarzwald-Baar, Waldshut, Lörrach and the French départements of the Haut-Rhin and the Bas-Rhin.

The district is named after the Breisgau, a historical territory, and the High Black Forest (Hochschwarzwald).

The eastern part, the upper reaches of the Danube and Neckar, came under the Carolingian dominion of the Ahalolfings.

The Swabian princes of Fürstenberg dominated the Baar, while the area south of Freiburg, the Markgräflerland, ended up with the margraves of Baden.

In the course of the history the Amtsbezirke were changed several times, until in 1936 only those of Freiburg, Müllheim, Neustadt im Schwarzwald and Staufen were left.

The population figures are based on censuses (1987) or official updates by the Baden-Württemberg State Office of Statistics (only main residences).
