The Breitenberg near Sankt Martin in the Rhineland-Palatinate county of Südliche Weinstraße is a hill, 545.2 m above sea level (NHN),[1] and subpeak of the Kalmit, the highest mountain in the Palatinate Forest.

Its summit rises 1.3 km northwest of Sankt Martin and 3 km west-northwest (both as the crow flies) of Maikammer, whose joint territorial boundary runs over the completely wooded hill.

535 m), the Wetterkreuzberg (400.7 m), the Taubenkopf (603.8 m), the Hüttenberg (620.1 m) and the Kanzel (531.7 m) the Breitenberg is one of the subpeaks of the Kalmit massif (672.6 m)[2].

It is located in an exposed location on the eastern edge of the Haardt, so that it appears as a prominent hill despite its relatively low height above places in the Upper Rhine Plain.

The Kalmithöhenstraße, which runs inter alia past the Kalmit to the Hüttenhohl and is part of the Landesstraße 515 from Maikammer, crosses the highland northwest of the Breitenberg summit.
