Bieber is a river of Hesse, Germany. It flows into the Rodau in Mühlheim am Main. The Bieber rises northeast of Dreieich-Götzenhain in the field "Am green Born" just west of a farm on Kirchborn and flows from there in the northeast. It takes on the right swelling branch Kirchborn and then pulls through the southern tip of the forest Lichteichen where it flows through the Wollwiesenteich, where they learn from the left another inflow. After re-entry into the field corridor, it soon crosses the county town of Dietzenbach and enters behind it between Dietzenbach and Heusenstamm back into the forest, where she moves past the Patershäuser Hof by its long clearings, here called Liliengraben.
