The Taunus is a mountain chain in Hesse, Germany. It is bounded by the river valleys of Rhine, Main and Lahn. On the opposite side of the Rhine the mountains are continued by the Hunsrück.

The highest peak is the Großer Feldberg (880 m), followed by the Kleiner Feldberg and the Altkönig (798 m) with the remains of a late Iron Age Hill fort (La-Tène A, ca. 400 BC) near the summit.

The Roman Limes was built across the Taunus. The Saalburg , a restored Roman castellum, now houses a museum. After the fall of the limes 260/61 AD the Alamanni settled here. For this reason there are some Alemannian gravesites in the southern foothills of the Taunus ( Eschborn). The area became Frankish after the Battle of Tolbiac.
