Moosach is a municipality in the Upper Bavarian district of Ebersberg and a member of the Verwaltungsgemeinschaft (administrative community) of Glonn.

The community lies in a picturesque setting in an ice-age moraine landscape about 500 m in elevation and lends itself well to hiking.

Moosach comprises a number of surrounding hamlets and lone homesteads such as Falkenberg (with a stable and a beergarden), Baumhau, Altenburg and Berghofen.

In 1990, Moosach celebrated 1,200 years of existence, witnessed in a donation document of the Roman Catholic Archdiocese of Munich and Freising.

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