The Vomperbach is a river of Tyrol, Austria, a tributary of the Inn.
The Vomperbach rises in the Karwendel mountain range, close to the source of the Isar and flows first from west to east. In the {{ill|Vomper Loch|de||fr}}, a tributary valley of the Inn that is partly a ravine, the Vomperbach changes its course southward and finally passes as boundary between the villages of Vomp and Terfens, where it discharges into the Inn. It has a length of {{convert|17|km}}.
Water quality
In its upper course in the Vomper Loch, the river is partly covered by detrital, therefore almost invisible and a water quality cannot be measured. Below until its mouth the water quality remains constantly grade A and provides the villages with drinking water.
