The Fuchskaute is an extinct volcano and, at 657.3 m above sea level (NHN)[1], the highest mountain of the Westerwald and the county of Westerwaldkreis in the German state of Rhineland-Palatinate.

It is about halfway between Bad Marienberg in the west and Breitscheid in the east and lies in the parish of Willingen.

Just under 3 km north-northeast is the tripoint of the states of Hesse, North Rhine-Westphalia and Rhineland-Palatinate.

There used to be an observation tower on the Fuchskaute from where views of the Westerwald and other local countryside could be enjoyed.

Amateur radio services formerly operated two transmission towers on the south top of the Fuchskaute.
