Wellersberg, Mountain summit in Siegen, Germany

Wellersberg is a 346-metre-high hill on the city territory of Siegen in North Rhine-Westphalia, about 1.5 km northwest of the town centre on the Siegberg. Its summit is unbuilt, the Hermelsbach cemetery lies on the western slope and the DRK Children's Clinic on the eastern slope.

The mountain was mined during the 19th century with operations such as the Friedrichshoffnung and Eisenberg mines that helped drive industrial development in the region. This mining activity shaped the economic history of Siegen at that time.

The western slope holds the Hermelsbach cemetery, while the DRK Children's Clinic Siegen stands on the eastern slope. The summit itself is unbuilt, so both institutions sit below the ridge line. The mountain lies about 1.5 km northwest of Siegen's city centre, on the Siegberg.

The L562, called Freudenberger Straße, runs between the Wellersberg and the neighbouring Fischbacherberg (371 m) and links Freudenberg with Siegen. The summit itself is unbuilt, so there is no infrastructure up top; the western slope holds the Hermelsbacher Friedhof and the eastern slope the DRK-Kinderklinik Siegen.

The summit itself is unbuilt, but both flanks carry institutions: the Hermelsbacher Friedhof on the west slope and the DRK-Kinderklinik Siegen on the east. The hill also held mines such as Friedrichshoffnung and Eisenberg, and the L562 (Freudenberger Straße) passes between it and the 371 m Fischbacherberg.
