The Hierdense Beek is a lowland stream on the Veluwe. It rises at the Uddelermeer and Bleeke Meer near Uddel and flows via Staverden and Leuvenum into the Veluwemeer near Hierden. Along its course it is one system, but with different names: at Staverden it is called the Staverdense Beek, on the Leuvenum estate the Leuvenumse Beek, and further downstream towards Hierden the Hierdense Beek.

The stream is partly natural and partly man-made and is considered one of the longest and best-known springs-and-lowland streams of the Veluwe. Its valley, flanked by push moraines, formed on an impermeable boulder clay layer from the penultimate Ice Age, causing rain and groundwater to collect into streams. Written sources already mention the brook and its branches in the Middle Ages; in 1368 the Leuvenumse Beek was leased out with the right to dig it and to build watermills. In the 18th century several paper mills were established along Staverden and Leuvenum, for which new channels and spring heads were constructed.
