Mohnenfluh, Mountain summit in Vorarlberg, Austria

Mohnenfluh is a 2,542-metre summit in the Lechquellen Mountains of Vorarlberg, the fourth-highest peak in the Schröcken area after the Braunarlspitze, Kleinspitze and Butzenspitze. Its south ridge rises above the Mohnen Saddle at 2,315 m, and the 2,412 m Juppenspitze stands in front of it to the northeast. The Bregenzer Ach springs on its eastern flank above Schröcken at about 2,400 m.

The name element "Mohn(-en)" may derive from Mond ("moon"), or, since Bergmähder lie nearby, from Mahd/Mähen ("mowing"). "Fluh" is an Upper German word for a broad or high rock mass, a crag or rock face, as recorded by Adelung. The sources give no founding date or historical event for the summit.

The neighbouring Juppenspitze (2,412 m) is counted as a separate summit, and south of the saddle stands the Zuger Hochlicht (2,371 m) with the ruins of an old cable-car station.
