Urff
Urff is a  tributary of the river Schwalm in Waldeck-Frankenberg and Schwalm-Eder-Kreis, North Hesse (Germany). It flows into the Schwalm near Niederurff.

History 
The Urff starts in the Kellerwald. Its source lies west-southwest of the Bad Wildungen district of Hundsdorf and east-northeast of the Haina district of Löllbach on the transition area between Große Aschkoppe (639.8 m) in the southeast, Alter Koppe (591.4 m) in the southwest, and Wölftekopf (567.1 m) in the north-northeast.

The Urff runs through the wooded Kellerwald-Edersee Nature Park in an eastward direction and through Hundsdorf, where it bends to the south-east towards Armsfeld. Below Armsfeld, south of Auenberg (610.7 m), the creek turns east and flows past the villages of Fischbach and Bergfreiheit, the ruins of Löwenstein Castle (341.2 m), and Oberurff-Schiffelborn after Niederurff.

The confluence of the Urff in the Schwalm is in the Löwensteiner Grund south-east of Niederurff at a height of about 193.5 m; to the northeast rises the Altenburg (432.7 m).
