The Bille river is a small, slow-flowing river in Stormarn, Schleswig-Holstein. Its spring is near Linau , north of the Hahnheide Forest. It then flows south of Trittau, representing the border between Stormarn and Lauenburg, continues south of Reinbek and reaches the river Elbe near Billwerder. A lot of old estates and tasteful parks are laid along its riverbank.
The Bille is one of three rivers floating through the city of Hamburg.
