Baiern is a community in the district of Ebersberg, Upper Bavaria, Germany. It is a member of the administrative community of Glonn.
The community's name is pronounced the same way as the German name for Bavaria, although it is spelt differently. This is most likely derived from the old way of spelling Bavaria in German.
