The Erlenbach is a stream, over 9 km long, in the South Palatine Wasgau region of the German state of Rhineland-Palatinate.

Initially the stream flows eastwards passing through the parish of Oberschlettenbach, its two headstreams meeting after 2 km, the smaller brook emptying from the right into the bigger one.

Immediately east of the source area lies the Südliche Weinstraße Wildlife Park and the castle of Lindelbrunn.

Drachenfels Castle, 3 km west of the middle reaches of the stream, was destroyed in 1523, because part of it had belonged to the rebel knight Francis of Sickingen.

The chapel was commissioned by the nearby Weissenburg Abbey and was completed in 1462 in order to enable the miners of the iron ore pit at the Bremmelberg the opportunity to go to church.
