The Seltenbach is a 5.3-kilometre-long (3.3 mi) stream and an orographically right-hand tributary of the Eisbach in the northeastern part of the Palatine Forest in the German state of Rhineland-Palatinate.

The Seltenbach rises at a height of about 282 m above sea level (NHN) northwest of the hamlet of the Nackterhof [de] which belongs to the municipality of Neuleiningen.

The source on the northwestern slope of a 320 m-high hill, called the Kleiner Donnersberg, lies on the territory of the municipality of Hettenleidelheim.

The stream initially flows in a north-northwesterly direction along the B 47 federal highway and enters the eastern edge of the built-up area of Hettenleidelheim, before it bends away to the northeast.

East of the village itself the Seltenbach empties into the Eisbach from the right at a height of about 160 m. A few metres below are the mouths of the Rodenbach and the Quirnheimer Bach [de].
