Döbling is located in the northwest of Vienna and spans the slope of the Wienerwald (Vienna Forest) to the Danube and the Danube Canal that make up the border of the district in the east. The Danube forms the border between Döbling and the district Floridsdorf, and the canal forms the border to the district Brigittenau. At the Gürtel Bridge, over the Donau Canal, the district border splits off and separates Döbling in the south along the Vienna Belt from the district Alsergrund. At the Schrottenbachgasse the district border branches towards the northwest and separates Döbling from the district Währing along the line Währinger Park-Hasenauerstraße-Peter Jordan Straße-Starkfriedgasse -Sommerhaidenweg. There is then a short border to the district Hernals at the edge of Vienna.
