Aßling (spelled with the German ß) is a municipality in the district of Ebersberg, Upper Bavaria, Germany.

The place belonged to the Rentamt [bar; de; es] of Munich and the Court of Swabia of the Electorate of Bavaria.

The community in its current form came into being in 1818 with the constituent communities of Adelpolt, Ametsbichl, Aßling, Ast, Bichl, Haar, Holzen, Längholz, Langkofen, Martermühle, Niclasreuth, Obstädt, Osterwald, Pörsdorf, Pürzelberg, Rammel, Sixtenreit, Sonnenreit, Steinkirchen, Stelzenreit, Tegernau, Thaldorf and Wollwies.

In 1978, as part of administrative reform, the formerly separate community of Loitersdorf was amalgamated with Aßling along with its constituent communities of Dorfen, Hochreit, Lorenzenberg, Loitersdorf, Obereichhofen, Untereichhofen, Pfadendorf, Hainza, Pausmühle, Setzermühle and Siglmühle.

The official German blazon (In Blau ein sechsspeichiges silbernes Rad, beiderseits und unten begleitet von je einer silbernen Blume mit goldenem Butzen) says that the flowers are on each side and underneath, but the usual interpretation is to have the flowers surrounding the wheel in the form of a triangle pointing down.
