The Zeller Blauen (more rarely: Hochblauen) is a mountain, 1,077.1 m above sea level (NHN), in the southern Black Forest in Germany. It belongs to Zell im Wiesental in the Baden-Württemberg county of Lörrach. The mountain, with its steep slopes to the south, west and east, dominates the Wiese valley north of the town of Zell and towers above it by more than 600 metres. To the north a ridge runs from the forested summit region of the Zeller Blauen, between the Kleines Wiesental in the west and the Wiesental in the east, to the Belchen 10 kilometres away.
