The Dent de Vaulion is a 1'483 m high, distinctive mountain in the Vaud Jura in Vallorbe in Switzerland. The ridge shows a highly asymmetric topography: To the north- west and north falls by up to 200 m high cliffs steeply, while the slopes to the south and southeast have a relatively low tendency. Hence his naming ( " Vaulion - tooth" ) is derived.

Dent de Vaulion is bordered on the west by the valley of the Ruisseau des Epoisats, on the north by the valley basin of Vallorbe, in the east and southeast by the syncline Vaulion in which springs from the Nozon, and on the south by the pass of Petra Felix at level crossing of L' Isle on the Col du Mollendruz in the Vallée de Joux. Optical is the Dent de Vaulion the northeastern conclusion of the Valley Vallée de Joux, although between this valley and the mountain remains the separate Talfurche the Ruisseau des Epoisats.

The geological structure of the Dent de Vaulion based on a anticlines whose bedrock material derived from marine sediments of the upper Jurassic ( Malm ). Along the strike-slip fault, which runs from Mont Richer on Vallorbe to Pontarlier, the anticline of the Dent de Vaulion was moved to the north. Therefore, the fold structure of the Jura mountains in this area is highly disturbed.

The slopes of the Dent de Vaulion are mainly passed with spruce forest, while the peak area shows the sparse grass vegetation of the high Jura. This easily accessible summit is a popular excursion destination from which offer interesting views of the Vallée de Joux, the basin of Vallorbe and in clear weather to the Alps. In winter, on the southeast slope of the mountain, a ski lift in operation.
