Gammelsdorf is a municipality in the district of Freising in Bavaria in Germany.
It was the site of the 1313 Battle of Gammelsdorf.
Until the mid-1990s Gammelsdorf was home of the "Circus", formerly known as the world's first village cinema, and later a nightclub where many famous artists and rock bands held concerts, most notably Nirvana.
