The Weissfluhjoch ({{convert|2693|m|ft|abbr=on}}) is a summit southeast of the Weissfluh ({{convert|2843|m|ft|abbr=on}}) situated in the Plessur Range in Graubünden, Switzerland. Since 1932, a funicular railway (the Parsennbahn) leads to its summit from Davos.

On the Weissflujoch, there used to be several laboratories of the Institute for Snow and Avalanche Research, a division of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL).[http://www.slf.ch/ueber/standorte/weissfluhjoch/index_EN "Weissfluhjoch test site"]. sfl.ch.
